Andy Burnham has been warned that Britain faces Russian retaliation over its support for Ukraine.
Security experts have told the Prime Minister to be prepared for a ‘direct response’ from Vladimir Putin. The Kremlin is set to target the UK, sources said, after miscalculating Mr Burnham’s commitment to Kyiv.
Putin had been advised the new incumbent in No10 would be ‘softer than [Sir Keir] Starmer’.
But the Russian president’s hopes were dashed by the Prime Minister’s moves to fortify the UK-Ukraine military alliance in recent weeks, swapping missile blueprints and battlefield AI with Moscow‘s enemy.
Putin is also believed to be coming under pressure within Russia to challenge Britain’s increasing involvement in the conflict.
The shock alert for the PM came as the head of the US’s Central Intelligence Agency (CIA) made an emergency visit to Moscow yesterday.
It was reported that spy chief John Ratcliffe issued a warning to the Kremlin not to escalate the conflict in Ukraine, either by using a nuclear weapon or targeting Kyiv’s Western allies.
The ‘just don’t do it’ advice was based on US intelligence that Russia is primed to act immediately and dramatically after its campaign on the battlefield stalled again.

UK security chiefs were on Tuesday night primed for a Kremlin attack on Britain – either towards Mr Burnham or by targeting defence sites.
A senior source told the Daily Mail: ‘The question being asked is, “How long do we keep poking the bear before it bites?”
‘An attack on the UK’s defence and security infrastructure is inevitable, based on our high-profile support for Ukraine.
‘Ourselves and the French are front and centre, and Burnham’s visit to Kyiv and his forthright stance will have been noticed at the Kremlin.
‘There had been some optimism in Moscow that he would be softer than Starmer on Ukraine.
‘That was not the case. Russia will want to make a statement, through actions rather than words. That could be a drone attack, or an arson attack. There are Russian sleeper cells in this country that could do either.’
The source added: ‘Russia is testing our security infrastructure on a daily basis… Something bigger is only a matter of time. Russia just needs to keep it low enough to avoid a military response by Nato.’

A Kremlin adviser brazenly suggested factories producing drones for Ukraine could be targeted by ‘unknown sources’.
Former Russian deputy foreign minister Andrei Fedorov said he could not ‘100 per cent exclude’ the prospect of ‘semi-military’ action against Britain following Mr Burnham’s visit to Kyiv on Monday.
During the trip, which was the Prime Minister’s first overseas since entering No10, the UK reiterated its ‘unwavering’ support for Ukraine, which in turn handed over what officials have called a ‘goldmine’ of battlefield data to help bolster British security.
Mr Fedorov said ‘sooner or later, there might be not only verbal but maybe some visible reaction from Russia towards the UK’.
Asked to elaborate on what this might look like, he said: ‘It might be so-called technical reaction, maybe some hackers attack from [an] unknown source.
‘There might be different political steps and I cannot exclude 100 per cent that there might be some semi-military [action].’
Pressed to define ‘semi-military’, he told the BBC’s Newsnight: ‘For example, something might happen with enterprises, with the factories which are producing drones for Ukraine.’
Asked whether this meant factories in Britain being attacked militarily, the Kremlin adviser said: ‘They could be attacked, not by Russia, but by… from unknown sources.’

Andy Burnham Warned of a Russian Attack as Britain Stands Firmly Behind Ukraine
Britain is facing a new period of tension with Russia after Moscow warned that the United Kingdom could face serious consequences for its continued support of Ukraine. The warning comes at a particularly sensitive moment for British Prime Minister Andy Burnham, who has made clear that his government intends to remain firmly behind Kyiv despite growing pressure from the Kremlin.
The situation has raised concerns about whether Britain could become a more direct target of Russian retaliation. However, it is important to distinguish between a Russian threat and evidence of an imminent military attack. At present, there is no confirmed evidence that Moscow is preparing an immediate conventional attack on Britain. Instead, British officials and security experts are increasingly concerned about possible cyberattacks, sabotage, espionage and other forms of so-called “grey-zone” aggression.
The latest tensions intensified after reports that Ukrainian forces had used British-made drones in long-range attacks against targets inside Russia. Moscow accused London of deliberately escalating the conflict and warned that Britain’s growing involvement could bring consequences. Russia’s embassy in London said that the deeper Britain’s involvement became, the higher the price it would pay.
Burnham, however, has refused to back down. He has repeatedly insisted that Britain will continue to support Ukraine. In response to the Russian warning, he said that the United Kingdom would support Ukraine “100%” and stressed that Britain would not abandon Kyiv during what he described as Ukraine’s hour of need.
His position represents a continuation of Britain’s broader policy since Russia launched its full-scale invasion of Ukraine in February 2022. Successive British governments have provided military equipment, training, intelligence and financial assistance to Ukraine. Under Burnham, London has indicated that it intends to maintain this support despite the increasing risks.
The issue became even more serious during Burnham’s recent visit to Kyiv. On his first foreign trip as prime minister, he met Ukrainian President Volodymyr Zelenskyy and joined other European leaders in demonstrating solidarity with Ukraine on its Independence Day. The visit came as Russian missile and drone attacks continued to put pressure on Ukrainian cities and infrastructure.
During the visit, Britain announced further assistance designed to strengthen Ukraine’s ability to produce long-range missiles. London also agreed to share information about British-made components used in long-range weapons. Russia reacted angrily, with Kremlin spokesman Dmitry Peskov accusing Britain of adding “fuel to the fire.” Moscow also indicated that it was gathering information about missile-production facilities in Ukraine.
For Burnham, however, the argument is straightforward. He believes Ukraine has the right to defend itself against Russian aggression, and he has rejected the idea that British support should end simply because Russia threatens retaliation.
His position places Britain in a difficult strategic situation. On one hand, London wants to demonstrate that threats cannot force European countries to abandon Ukraine. On the other hand, British officials must consider the possibility that Russia could respond in ways that extend beyond the battlefield in Ukraine.
A direct Russian attack on Britain would be an extremely serious escalation. The United Kingdom is a member of NATO, meaning that an armed attack against Britain could have consequences far beyond the two countries involved. For this reason, Russia is generally more likely to consider actions that remain below the threshold of open warfare.
Cyberattacks are one possible area of concern. Russia has previously been accused by Western governments of using cyber operations against government institutions, businesses and critical infrastructure. Britain is also increasingly concerned about the security of energy networks, communications systems and other important infrastructure. Recent British preparations for national emergencies reflect a broader recognition that modern conflicts do not necessarily begin with tanks crossing borders.
Sabotage and covert operations are another potential threat. Security analysts have warned that Russia could seek to intimidate or disrupt countries supporting Ukraine through clandestine activities. Such operations might include attacks on infrastructure, espionage, disinformation campaigns or attempts to interfere with political and economic systems.
This makes the current situation different from the traditional idea of an approaching invasion. When people hear that Britain could face a Russian “attack,” they may imagine Russian missiles falling on London or Russian troops landing on British territory. There is currently no reliable evidence that such an attack is imminent. The more realistic concern is a gradual increase in hostile activity designed to pressure Britain into changing its policy.
Moscow’s rhetoric is part of that pressure. By warning Britain that it will face consequences for supporting Ukraine, Russia is attempting to make British policymakers consider the potential costs of further involvement. The Kremlin has repeatedly argued that Western military assistance prolongs the war and increases the possibility of a wider confrontation.
Britain, however, has adopted the opposite argument. Burnham and his government maintain that supporting Ukraine is necessary to prevent Russian aggression from succeeding. During his visit to Kyiv, Burnham described Russia’s attacks on Ukrainian civilians as a campaign of terror and urged international allies to provide more air-defence systems.
One of the most urgent problems facing Ukraine is its shortage of air-defence missiles. Russian forces have continued launching large numbers of missiles and drones against Ukrainian targets, particularly as Kyiv prepares for another difficult winter. Zelenskyy has appealed to Western countries for additional systems, including American-made Patriot interceptors.
Burnham has said that he intends to take Ukraine’s request for additional Patriot missiles to US President Donald Trump. The British prime minister is expected to attend the United Nations General Assembly in New York next month, where he could meet Trump for the first time in person.
The diplomatic challenge is therefore becoming increasingly complicated. Britain wants the United States and European allies to provide greater military assistance to Ukraine, while simultaneously attempting to prevent the conflict from developing into a direct confrontation between NATO and Russia.
For ordinary British citizens, the situation can understandably appear frightening. Headlines about an impending Russian attack can create the impression that war is about to arrive on British soil. Yet the available evidence suggests a more complicated picture. The immediate threat is better understood as a broad national-security challenge rather than proof that a conventional Russian invasion of Britain is imminent.
The British government has therefore begun emphasizing national resilience. Citizens are being encouraged to consider how they would cope with emergencies such as cyberattacks, extreme weather or disruptions to essential services. The government has discussed encouraging households to keep basic supplies such as bottled water and canned food.
Such preparations do not necessarily mean that officials expect war. Instead, they reflect a changing understanding of national security. In the modern world, governments must prepare for a variety of emergencies that can occur with little warning.
At the same time, Britain’s relationship with Russia is becoming increasingly confrontational. Diplomatic relations have deteriorated significantly since the beginning of the Ukraine war. Both sides have accused the other of escalation, while Britain and its allies continue to impose economic sanctions and provide military assistance to Kyiv.
Burnham’s decision to maintain support for Ukraine therefore carries political as well as military consequences. He is attempting to demonstrate that Britain will not be intimidated by Russian threats. His message is that Ukraine’s sovereignty and European security are important enough to justify continued British involvement.
Whether this strategy will contribute to a long-term peace remains uncertain. The war has already lasted for years, and diplomatic efforts have repeatedly struggled to produce a lasting settlement. Russia continues to demand security guarantees and concessions, while Ukraine insists on its right to defend its territory and determine its own future.
For Britain, the central challenge is to support Ukraine without allowing the conflict to spiral into a direct war between NATO and Russia. That requires a careful balance between deterrence and restraint.
Andy Burnham has so far chosen firmness rather than retreat. His message is that Britain will continue to stand with Ukraine despite Russian warnings. Moscow, meanwhile, has made clear that it regards Britain’s military assistance as increasingly hostile.
The coming months will therefore be crucial. If Russia continues escalating its threats and Britain continues expanding its support for Ukraine, pressure between the two countries is likely to remain high. Nevertheless, claims of an imminent Russian military attack on Britain should be treated carefully. The evidence currently points more strongly toward the risks of cyberwarfare, sabotage, espionage and political intimidation than an immediate conventional invasion.
Ultimately, Burnham faces a difficult responsibility. He must protect British national security while maintaining Britain’s commitment to Ukraine. His response to Russia’s warnings suggests that he believes backing down would reward aggression. Whether that determination can help Ukraine while keeping Britain out of a wider war will be one of the most important foreign-policy tests of his premiership.
For now, the message from London is clear: Britain intends to remain alongside Ukraine. The message from Moscow is equally serious: Russia believes Britain’s growing involvement carries risks and has threatened consequences. Between these two positions lies a dangerous diplomatic confrontation—one that will require strong leadership, careful judgment and continued efforts to prevent the war in Ukraine from becoming an even larger conflict.
