FORMER Foreign Secretary Boris Johnson joined the Prime Minister in rejecting calls for a second Brexit referendum.

Writing in the Telegraph, he said: “A second referendum would provoke instant, deep and ineradicable feelings of betrayal.”

Mr Johnson said the idea that the Government would hold a fresh Brexit poll was “sickening”.

The PM is set to address to the Commons later today and is expected to say that a new national poll would do “irreparable damage” to the integrity of British politics.

The move comes after close allies of Mrs May distanced themselves from reports that they were manoeuvring to bring about a fresh referendum.

Solicitor General Robert Buckland became the latest senior Tory to float the idea of a free vote in the Commons on Brexit.

May will say: “Let us not break faith with the British people by trying to stage another referendum.

“Another vote which would do irreparable damage to the integrity of our politics, because it would say to millions who trusted in democracy, that our democracy does not deliver.

“Another vote which would likely leave us no further forward than the last.

“And another vote which would further divide our country at the very moment we should be working to unite it.”
