PRIME MINISTER Theresa May faces fresh pressure after Foreign Secretary Boris Johnson’s warning of a Brexit “meltdown” was leaked, throwing an already chaotic Cabinet into further disarray.

Mr Johnson said at a private dinner on Wednesday night that there was a risk Brexit “will not be the one we want” and would keep Britain “locked in orbit” around the European Union.

At the gathering of the Conservative Way Forward, a Thatcherite campaign group, he branded the Treasury the “heart of Remain” and claimed negotiations were approaching a “moment of truth.”
