Donald Trump has promised to prosecute those who leaked intelligence about the Manchester bomber to the US media, after Theresa May warned the leaks could undermine the “special relationship”.

The US president aid the US leaks are "deeply troubling" and has vowed "to get to the bottom of this".

The Prime Minister, in common with the police and British intelligence agencies, is furious that sensitive material about the investigation has repeatedly been handed to the US media, which ministers say risks compromising the fast-moving inquiry.
