The Home Secretary expressed her annoyance at US intelligence services for releasing details of the Manchester bomber, as the investigation continued into the attack which killed 22 people, including children, and left 120 injured. Rudd’s dismay at the leaks of classified information by the US, Britain’s foremost intelligence partner, is one shared by other continental allies. One un-named Belgian counterterrorism official told Buzzfeed News that: “You know you are trading the additional resources they bring for a chance of increased leaks. “In this case, I suspect the Brits are livid, I know we would be, to have a suspect ID'd before they're ready, and obviously the recent performance of the Trump administration on leaking sensitive information can't be far from anyone's mind if they examine [the situation].” US President Donald Trump has come under fire domestically for revealing sensitive information to Russian officials during a visit by Foreign minister Sergey Lavrov.

Speaking to Radio 4’s Today programme, Ms Rudd said: “Yes quite frankly the British police have been very clear that they want to control the flow of information in order to protect operational integrity, the element of surprise. “It is irritating if it gets released from other sources. “I have been very clear with our friends that that should not happen again.” When asked if leaks had “compromised” the investigation into the Manchester attacker, the Home Secretary added she “wouldn’t go that far”.

She said: “I can say that they are perfectly clear about the situation and that it shouldn’t happen again.” During her interview the Home Secretary also claimed it “seems likely” that the Manchester killer was not acting alone during his attack. She also confirmed the attacker was known by security services “up to a point”. “The security services will know a lot of people that does not mean they are expected to arrest everybody they know,” she said.

“It is somebody who they had known before and I am sure when this investigation concludes we will be able to find out more.” On Tuesday evening, Theresa May made the announcement that the UK terror threat level was raised to ‘critical’ meaning an attack could be ‘imminent’ following an emergency COBRA meeting. Mrs May admitted that it was possible a “wider group of individuals” could have been behind the Manchester Arena attack, which occurred at the end of an Ariana Grande concert.
