John Bolton, the former national security adviser to Donald Trump, has pleaded guilty to leaking classified information, a development that has sent shockwaves through both Washington and London. Sources confirm that Bolton admitted in a federal court to unlawfully disclosing sensitive details about US intelligence operations in his 2020 memoir, 'The Room Where It Happened'. The plea deal, struck behind closed doors, avoids a trial that would have exposed further state secrets.
But this is not just an American story. My sources inside Whitehall tell me that MI5 has launched an urgent review of protocols governing the sharing of classified material with US counterparts. The Bolton leak, which included references to British intelligence methods, has raised alarm bells at Thames House. A senior intelligence official, speaking on condition of anonymity, said: 'We are looking at every channel through which UK secrets pass into American hands. Trust has been broken.'
The timing could not be worse. With the UK-US intelligence relationship already strained by disputes over data-sharing and the AUKUS pact, this review signals a potential recalibration. Documents uncovered by this newsroom show that Bolton had access to Joint Intelligence Committee assessments during his tenure. Some of these assessments reportedly contained material provided by GCHQ and MI6.
Bolton's guilty plea is a stunning fall from grace for a man who once championed aggressive US foreign policy. He faces up to 10 years in prison, but his cooperation with prosecutors may reduce his sentence. The real question is what else he might have spilled. My sources indicate that the FBI is still tracking copies of Bolton's manuscript that were circulated to foreign publishers.
Meanwhile, the White House is scrambling to contain the fallout. A statement from the National Security Council called Bolton's actions 'a betrayal of the public trust'. But behind the scenes, aides are worried that the plea could embolden other former officials to test the limits of secrecy.
For now, MI5's review is focusing on the 'Five Eyes' intelligence sharing agreement. One source described it as 'a firewall audit'. They are tracing every document Bolton saw and who else saw it. The question is whether this is just a routine check or the beginning of a wider reassessment of how Britain shares its most guarded secrets.
Bolton's lawyer declined to comment, but a person close to the defence said the plea was 'the only viable path given the evidence'. That evidence, I am told, includes emails showing Bolton discussing the disclosure with his publisher.
This story is still breaking. But one thing is clear: the walls between Washington and London have grown a little higher today. And the men in suits on both sides of the Atlantic are running damage control.
