Labour is set to funnel millions of pounds from union members into its own coffers through a back door scheme hidden in its Employment Rights Act, the Daily Express can reveal. Analysis seen by this paper shows that Labour could gain an extra £4.3 million a year from a clause buried in the 2025 Employment Rights Act which comes into force next month.
The clause would mean Union members would need to opt out of political donations, rather than the current system which sees them choose to opt in, in a move critics have branded a “stitch-up”.
Former Tory Leader, Sir Ian Duncan Smith told the Express: “The so-called Employment Rights Act isn’t about protecting workers – it’s about quietly funnelling millions of pounds to Labour through the back door.”
He added: “By auto-enrolling union members into political funding, it takes money from working people without proper consent and turns it into a taxpayer-subsidised Socialist war chest. It’s a stitch-up that undermines already fragile businesses and erodes trust in our democracy.”
The Act removes the requirement for trade unions to remind members of their right to opt out of contributing to the union’s political fund. It also automatically opts-in new members by default, meaning workers will have to actively choose not to contribute rather than actively choosing to contribute.
Political funds are legally ring-fenced accounts held by unions and used for political activity, with many trade unions donating huge sums to the Labour Party. The move could put Labour in line to receive a vast influx of donations.
When the opt-in policy was introduced in 2016, experts projected it could cost Labour as much as £6million in foregone donations, as political fund balances were expected to fall dramatically.
Nearly a decade on, data seen by this paper now suggests that requiring union members to opt out rather than opt into paying the political fund levy could make over £4million in additional political fund cash available to be donated to Labour.
In 2024, the 11 affiliated unions to Labour had combined income to their political funds from members of £18.5million, and a collective political war chest of £43.7million.
On average, 63% of union members opted in to contributing to the political fund, down from the 90% average in 2016.
If opt-ins return to the 2016 rate of 90% under the new automatic enrolment system, that would project as an additional £4.3million in political fund revenue for trade unions.

All of that cash could be passed on to Labour in the form of affiliation fees or donations.
The Act is under increasing scrutiny from the public and politicians, including over measures which would see businesses with as few as 21 employees forced to grant unions access on a weekly basis.
Section 62 of the Employment Rights Act 2025 alters arrangements for new members joining a trade union, so they are automatically opted in to contributing to the union’s political fund unless they expressly opt out by providing an opt-out notice.
It also removes the requirement for unions to remind members of their right to opt out of contributing to a political fund within eight weeks of submitting their annual return to the Certification Officer.
Unions are required to use their political funds for any political activity, including paying affiliation fees to Labour and any other donations.

FURY AT LABOUR PLOT TO FUNNEL MILLIONS FROM UNIONS INTO ‘SOCIALIST WAR CHEST’ – TAXPAYERS DEMAND ANSWERS AS POLITICAL FUNDING ROW EXPLODES!
A major political storm is brewing in Britain as fresh questions about the relationship between the Labour Party and the country’s powerful trade unions reignite a fierce debate over political donations, workers’ money, and the future of British democracy.
Critics are questioning whether millions of pounds contributed by ordinary trade union members are helping to strengthen Labour’s political machinery at a time when the government is already facing mounting criticism over taxation, public spending, immigration, and the cost of living.
The controversy has placed renewed attention on the financial relationship between Labour and its traditional union allies, raising an uncomfortable question for Prime Minister Keir Starmer: where exactly does the money going into British political parties come from, and who ultimately decides how it is used?
For decades, trade unions have played an important role in British politics.
Their financial support helped establish Labour as a political movement representing working people, and union donations have remained an important source of funding for the party.
However, the relationship has always attracted criticism from political opponents who argue that large institutional donations can create an unhealthy relationship between political parties and organisations with their own interests.
The latest controversy has intensified following renewed scrutiny of the scale of union political funds and the possibility of further changes to Britain’s political donation rules.
At the centre of the argument is the question of whether ordinary workers should be contributing money that ultimately supports a particular political party, especially when individual members may have very different political beliefs.
The debate is no longer confined to Westminster.
It concerns the rights of union members, the transparency of political donations, and whether the existing system gives ordinary workers sufficient control over the money collected in their name.
MILLIONS OF POUNDS UNDER THE SPOTLIGHT
The scale of trade union funding has become a major talking point.
An investigation published by the Workers of England Union on 15 September 2026 examined Electoral Commission donation records and estimated that reported trade union donations to Labour could total approximately £248 million since 2001.
The organisation also estimated that trade unions had raised approximately £495 million through political funds over a broadly similar period.
These are two separate figures and must not be confused.
The estimated £495 million represents money raised through political funds, not money donated directly to Labour.
Political funds can support a wider range of political activities, including campaigning, political publications, election-related expenditure, and contributions to political parties.
The distinction is important because the headline figures alone do not establish that all union political money has entered Labour’s accounts.
Nevertheless, the amounts involved demonstrate why greater transparency is an important issue for union members and taxpayers.
The investigation also highlighted that 21 trade unions had political funds, with 19 providing financial information, and that the reporting unions held approximately £29.4 million in those funds.
The figures have added another dimension to the argument over political influence and the role of organised labour in British elections.

A POLITICAL ALLIANCE THAT LABOUR CANNOT IGNORE
The relationship between Labour and trade unions is deeply rooted in British political history.
The Labour Party was founded with strong links to organised labour, and unions continue to provide financial support, campaign workers, political influence, and connections with millions of working people.
Major unions including Unite, Unison, and the GMB have historically been among Labour’s most important financial supporters.
Their leaders also participate in political discussions about employment rights, public services, wages, pensions, and industrial policy.
Supporters of the arrangement argue that union funding gives ordinary workers a collective political voice.
They point out that trade union donations are built from the contributions of many individual members rather than the wealth of a single billionaire.
Critics, however, question whether the system provides sufficient protection for members who disagree with their union’s political direction.
A worker may join a union for workplace representation, legal assistance, or protection against unfair treatment without wanting to support Labour or any other political party.
This is why the rules surrounding political funds are so important.
THE NEW POLITICAL DONATION BATTLE
The controversy has become even more significant following the debate over the enormous donations received by Reform UK.
In September 2026, Reform received two donations totalling £72 million from cryptocurrency billionaires Christopher Harborne and Ben Delo.
The donations triggered renewed calls for restrictions on political funding.
The Trades Union Congress responded by warning that large political donations from wealthy individuals threatened democratic accountability.
However, union leaders also argued that their own contributions should be treated differently because they originate from the collective subscriptions of ordinary workers.
This position has generated further debate.
Should a large union donation be treated as one institutional contribution, or should it be understood as the collective expression of thousands of individual members?
The question is particularly important because any future restrictions on political donations could affect the financial resources available to Labour and other parties.
Unite general secretary Sharon Graham has indicated support for limits on large individual donations, while arguing that trade union contributions are fundamentally different.
The debate has exposed disagreements within the union movement itself.
Some union leaders are concerned that restrictions designed to prevent wealthy individuals from influencing politics could unintentionally weaken workers’ collective political representation.
Others believe that political funding rules should be applied more consistently.

WHAT HAPPENS TO THE MONEY TAKEN FROM UNION MEMBERS?
One of the most controversial aspects of the system is how political contributions are collected.
Under British law, trade unions wishing to spend money on certain political activities must establish a separate political fund.
The fund must be approved through a statutory ballot, and unions must operate according to rules approved by the independent Certification Officer.
Political funds can be used for contributions to political parties, election campaigning, political publications, and other activities defined by legislation.
However, union members have legal rights concerning their contributions.
The government’s updated guidance, published on 25 August 2026, explains that members can opt out of contributing to their union’s political fund.
Importantly, members cannot be forced to contribute simply because they belong to a trade union.
The rules also protect members from being disadvantaged within their union because they choose not to contribute.
Changes introduced in February 2026 mean that new members joining unions with political funds are generally automatically included as contributors unless they opt out. Different transitional arrangements apply to existing members.
This has created further questions about whether workers fully understand the political funding arrangements attached to their membership subscriptions.
For critics, the system should be made considerably easier to understand, with clearer information about how much money is collected and where it goes.

STARmer FACES AN UNCOMFORTABLE POLITICAL QUESTION
The controversy presents a difficult situation for Starmer.
Labour has traditionally depended on financial and organisational support from trade unions, making the relationship an important part of the party’s political identity.
But the government must also demonstrate that it respects the rights of workers who do not necessarily support Labour.
The question is particularly sensitive when taxpayers are already concerned about government spending and the cost of living.
Many workers are struggling with household bills, mortgage payments, rents, and everyday expenses.
They may reasonably question why part of their union membership contribution is being used for political purposes rather than exclusively for workplace representation.
Union leaders respond that political campaigning is an important part of protecting workers’ interests.
They argue that employment legislation, wages, pensions, and public services are political issues that directly affect union members.
In their view, preventing unions from participating in politics would weaken the collective voice of working people.
This is a legitimate argument, but it does not remove the need for transparency and individual choice.
THE BIGGER QUESTION: WHO CONTROLS BRITISH POLITICS?
The dispute over union funding is part of a much larger argument about political influence in the United Kingdom.
Britain’s political parties depend on donations from different sources, including individuals, businesses, trade unions, and other eligible organisations.
Each source raises questions about influence and accountability.
The recent £72 million donation controversy involving Reform UK has demonstrated that enormous financial contributions can dramatically change the political landscape.
Meanwhile, Labour’s relationship with organised labour demonstrates how collective funding can provide established political parties with substantial resources.
The challenge is ensuring that neither wealthy individuals nor powerful institutions can exercise disproportionate influence over democratic decisions.
Voters deserve to know who finances political campaigns and whether those financial relationships create potential conflicts of interest.
A GROWING TEST FOR THE LABOUR GOVERNMENT
The political consequences could extend beyond the immediate controversy.
If Labour is perceived as protecting its traditional financial supporters while demanding restrictions on donations from other political organisations, opposition parties will inevitably question the consistency of its position.
Reform UK and the Conservatives are likely to use the issue to challenge Labour’s credibility on political transparency.
Meanwhile, union leaders will continue defending their members’ collective political voice.
This leaves Starmer facing an uncomfortable balancing act between maintaining Labour’s historic relationship with organised labour and demonstrating that his government supports fair political funding rules.
Ultimately, the issue should not be reduced to a simple argument about whether trade unions should support Labour.
The more important questions concern transparency, democratic consent, financial accountability, and the rights of individual members.
Workers should understand exactly what they are paying.
Union members should be able to exercise their legal rights without pressure or disadvantage.
Political parties should disclose their funding properly.
And the public should be able to examine the financial relationships that help shape Britain’s political system.
THE BIG QUESTION NOW IS WHETHER LABOUR WILL SUPPORT A POLITICAL FUNDING SYSTEM THAT APPLIES TRANSPARENT AND FAIR RULES TO EVERYONE – INCLUDING THE POWERFUL UNIONS THAT HAVE HELPED FINANCE THE PARTY FOR GENERATIONS.
With hundreds of millions of pounds potentially involved across the wider history of union political funding, the demand for answers is unlikely to disappear.
For Starmer, this is another test of political credibility.
For trade union leaders, it is a test of their commitment to representing all members, regardless of political beliefs.
And for ordinary British workers, the principle should be straightforward: if their money is being used to influence politics, they deserve to know where it goes, who controls it, and what choices they have.
