Speaking to The Telegraph, Lord Macdonald said that the draft Bill is “unclear” and it is “rule of law” that Britons should be able to understand whether what they are doing is legal or not.

He added that it could be an attempt by the trans lobby to get legislative changes “through the back door”.

He said: “I don’t think it criminalises anything that isn’t already criminal. The minister in the House of Lords was asked to explain what it was that was presently not criminal, that would be criminalised by the legislation.

“And he said that will come out in pre-legislative scrutiny, which, is unprecedented.

“If the minister can’t explain what it is that’s presently lawful that the Bill is going to make unlawful, that means there’s a serious problem with the Bill, frankly.”

Discussing the possibility of parents being imprisoned for talking to their children about transitioning, Lord Macdonald made clear that the legislation puts people in an “unacceptable situation”.

He told The Telegraph: “It talks about the use of psychological or emotional pressure. The problem with that is, when you’re having very sensitive discussions between, for example, parents and their children, or clinicians and their patients, it’s very difficult to understand what that means.

“There’s a basic principle called legal certainty, which is a very important part of the rule of law, which means that people need to understand when they are breaking the law and when they’re not breaking the law.”

He added: “But I think those concepts of psychological or emotional pressure mean that it would be very difficult for parents to know when they’re talking to their children or for clinicians to know when they’re talking to their patients, whether they’re breaking the law or not.

“And that is obviously an unacceptable situation. It’s completely contrary to the rule of law.”

Opposing the draft legislation, a group of Labour MPs and peers have scrutinising the law and could request amendments after interviewing witnesses.

Labour MP Steve Yemm has said although he supports banning “abusive and coercive conversion practices”, parents, teachers, and clinicians must be able to have an open discussion with children without the fear of being arrested.

He told The Telegraph: “Biological sex matters, and legitimate gender-critical beliefs must remain protected. I welcome the parliamentary scrutiny of the draft bill and hope it will address these concerns.

“I remain sceptical, but I have an open mind and would be willing to support legislation that protects people from genuine abuse while safeguarding freedom of belief and appropriate clinical care.”

The Government strongly rejects suggestions that ordinary conversations between parents and children would become criminal.

In a parliamentary answer on October 29, equalities minister Simon Lightwood said: “The draft Bill will not prevent parents from making choices on how to raise their children. We are preventing a very specific, severe form of abuse.”

Ministers insist the proposed law is intended to close gaps in existing legislation, particularly around psychological abuse, rather than punish parents for expressing concern or offering advice.

The draft Bill is undergoing parliamentary scrutiny and has not yet become law.

Labour’s Trans Conversion Therapy Bill Is ‘Contrary to Rule of Law’, Warns Former Top Prosecutor

Labour’s proposed ban on conversion practices has triggered a major legal and political controversy after a former Director of Public Prosecutions warned that the legislation could undermine a fundamental principle of British justice: the rule of law.

Lord Ken Macdonald, who led the Crown Prosecution Service between 2003 and 2008, has raised serious concerns about the wording of the Government’s draft Conversion Practices Bill. He argues that its definitions are insufficiently clear and could leave parents, teachers, religious leaders and healthcare professionals uncertain about whether ordinary conversations might expose them to criminal prosecution.

His intervention has intensified the debate over how Britain should protect transgender and LGBT+ people from abusive practices while safeguarding freedom of speech, parental responsibility and legitimate medical advice.

The controversy presents a difficult challenge for the Labour Government, which insists that the proposed legislation is designed to prevent abuse rather than criminalise ordinary discussions about sexuality or gender identity.

Former Top Prosecutor Questions the Legislation

Lord Macdonald’s criticism centres on the legal definition of an abusive conversion practice.

Speaking to The Telegraph, the former chief prosecutor argued that the proposed legislation does not clearly explain which activities would become criminal that are not already prohibited under existing laws.

He questioned why ministers were unable to identify precisely which currently lawful activities the legislation would make illegal.

His central concern is the concept of psychological or emotional pressure.

According to Macdonald, these terms could be difficult to interpret when applied to sensitive conversations between parents and children, or between healthcare professionals and patients.

He argues that the law must provide sufficient certainty for people to understand whether their conduct is lawful.

This principle is fundamental to the British legal system. Criminal offences should be defined clearly enough that individuals can understand what behaviour is prohibited.

Macdonald believes the draft legislation risks creating uncertainty in situations where people may hold different views about gender identity but are attempting to have legitimate discussions rather than subject anyone to abuse.

He has described the proposed wording as contrary to the rule of law.

What Does Labour’s Bill Actually Propose?

The Government published its draft Conversion Practices Bill in June 2026.

The proposed legislation applies to England and Wales and aims to prohibit abusive attempts to change or suppress an individual’s sexual orientation or transgender identity.

It is intended to protect people from practices involving coercion, threats, intimidation and psychological or emotional abuse.

The draft legislation identifies several forms of conduct that could contribute to an abusive conversion practice, including:

• Sexual or threatening words and behaviour.
• Controlling or coercive conduct.
• Economic pressure.
• Psychological pressure.
• Emotional pressure.

The proposed framework also includes criminal offences and protective orders intended to prevent individuals from being subjected to harmful practices.

The Government says the legislation is designed to address gaps in existing legal protections.

It argues that people should not be subjected to abusive attempts to change their sexuality or gender identity, regardless of whether those attempts are motivated by religious, ideological or personal beliefs.

However, critics believe the broad language surrounding psychological and emotional pressure requires further clarification.

Could Parents Be Criminalised for Discussing Gender Identity?

One of the most sensitive aspects of the debate concerns parents whose children are questioning their gender identity.

Some parents believe that children and teenagers should be able to explore questions about gender without being pressured towards any predetermined conclusion.

They argue that responsible parenting sometimes involves challenging a child’s assumptions, discussing medical consequences and encouraging them to consider different perspectives.

Critics of the proposed legislation fear that parents who express concerns about gender transition could face accusations of engaging in prohibited conversion practices.

They are particularly concerned about situations involving disagreement over social transition, pronouns, medical interventions and decisions about gender identity.

However, the Government strongly rejects the suggestion that ordinary parenting conversations would automatically become criminal offences.

Ministers say the proposed law is directed at abusive practices and includes safeguards intended to protect legitimate discussions.

The distinction between an honest conversation and abusive coercion is therefore central to the parliamentary examination of the bill.

The precise wording will matter enormously.

Religious Freedom and Freedom of Expression

Religious organisations have also raised concerns about the possible implications of the legislation.

Many religious communities have established teachings concerning sexuality, marriage and gender.

Their representatives argue that religious leaders must remain free to explain their beliefs, offer pastoral advice and discuss difficult moral questions without fear of criminal prosecution.

Freedom of religion and freedom of expression are protected under British law and the European Convention on Human Rights.

However, these rights are not unlimited.

They do not provide permission to threaten, abuse, intimidate or subject individuals to harmful treatment.

The challenge for Parliament is to ensure that the proposed legislation protects vulnerable people without unnecessarily restricting legitimate religious activities.

The Government’s own impact assessment acknowledges the importance of protecting religious freedom and individual expression.

It also states that parents, teachers, social workers and other people should be able to support individuals exploring their sexuality or gender identity without being caught by the criminal offences.

Whether the draft wording achieves that objective is one of the central questions now facing parliamentary scrutiny.

Labour Faces Opposition From Within Its Own Ranks

The controversy has also exposed disagreements within the Labour Party.

Labour MP Mary Glindon has publicly expressed serious reservations about the proposed legislation.

In an article published by Politics.co.uk on 11 November 2026, she argued that the draft bill could make it harder for people to seek appropriate help and support.

Glindon believes that the proposed definition of abuse is too broad and could create uncertainty around conversations that should remain lawful.

She argues that protecting vulnerable people must involve preserving the ability of parents, clinicians and other trusted individuals to discuss difficult subjects openly.

Other Labour MPs have also called for greater clarity.

Steve Yemm has expressed support for banning abusive and coercive conversion practices while emphasising that parents, teachers and healthcare professionals must retain the freedom to have open discussions with children.

These concerns demonstrate that the debate is not simply a confrontation between Labour and opposition parties.

There are also disagreements among politicians who support the underlying objective of protecting LGBT+ people but question whether the legislation has been drafted carefully enough.

Conservatives Withdraw Their Support

The proposed bill has also become a source of disagreement between Labour and the Conservatives.

Conservative leader Kemi Badenoch has raised concerns that the legislation could criminalise ordinary parental decisions and conversations about gender identity.

Her party has withdrawn its previous support for the proposed law, arguing that the current wording is insufficiently precise.

Equalities Minister Bridget Phillipson has criticised the Conservatives’ position, accusing Badenoch of abandoning protections for LGBT+ people.

Labour argues that the bill is necessary to protect individuals from abusive attempts to change their identities.

The Conservatives counter that genuine protection should not come at the expense of legitimate discussion, religious freedom or responsible clinical advice.

Both sides therefore present their arguments as questions of protecting vulnerable people, although they disagree fundamentally about the risks created by the proposed wording.

What Happens Next?

The draft bill is currently undergoing pre-legislative scrutiny.

This process allows parliamentary committees to examine the proposed legislation, hear evidence from legal experts and interested organisations, and recommend changes before a final bill is introduced.

This stage is particularly important because criminal legislation must be carefully drafted.

Parliament will need to examine the meaning of abuse, the role of psychological pressure, the position of parents and the safeguards available to healthcare professionals.

It will also need to consider whether existing criminal laws already cover certain forms of harmful conduct.

The Government has indicated that its intention is to create a targeted and proportionate framework rather than criminalise ordinary disagreements or conversations.

However, the criticisms raised by Lord Macdonald and other legal commentators demonstrate why detailed scrutiny is necessary.

Conclusion: Protecting Vulnerable People Without Undermining the Law

Labour’s proposed Conversion Practices Bill has opened an important debate about the balance between protecting LGBT+ people and preserving fundamental legal freedoms.

Lord Ken Macdonald’s intervention has placed particular emphasis on legal certainty, arguing that individuals must be able to understand exactly which actions could result in criminal prosecution.

Parents need confidence that they can discuss difficult subjects with their children. Teachers and healthcare professionals need clear professional boundaries. Religious communities must be able to express their beliefs peacefully.

At the same time, nobody should be subjected to violence, threats, intimidation or abusive attempts to change their sexual orientation or gender identity.

These objectives do not necessarily have to conflict.

The challenge for Parliament is to produce legislation that protects people from genuine abuse while ensuring that legitimate conversations, professional support and freedom of belief remain protected.

The proposed bill has not yet become law, and its final wording could change following parliamentary scrutiny.

Ultimately, the Government will need to demonstrate that its legislation is clear, proportionate and consistent with fundamental principles of justice.

Protecting vulnerable people is an important responsibility. Ensuring that criminal law is fair, predictable and understandable is equally essential.
