Theresa May’s master stroke is to pick a Cabinet that can deliver on the promise of Brexit

THERESA May delivered her “Brexit means Brexit” vow last night by handing the Foreign Office to Boris Johnson.

She coupled the daring move with the appointment of Thatcherite eurosceptic David Davis as the new Secretary of State for Brexit Negotiations.

They will work in harness with another leading Brexiteer, former Defence Secretary Liam Fox, as International Trade Secretary.

It was a master stroke in balancing a divided Tory party and the people over the future of Britain in Europe.

The appointments provide a stark warning to Brussels that Mrs May intends to make Brexit work in the British national interest, not Europe’s.

In another show of strength, the new PM booted George Osborne out of the Treasury.

He may have terrified referendum voters with his economic warnings, but she has lost a big beast in the Cabinet.

Osborne is replaced as Chancellor by Phil Hammond, who is the richest man in the Cabinet with a £10million fortune.

The Essex boy infuriated fellow eurosceptics by turning turtle and joining David Cameron’s Remain campaign.

But he was one of the first to back Mrs May and as a former Shadow Treasury Chief, he will fit quickly into the role.

He will be holding the purse strings as Britain forges its future as a sovereign trading nation — and will start with big cuts in corporation tax to lure foreign investors.

Mrs May moved Amber Rudd into her old job as Home Secretary. But it was her sensational promotion of Boris, who she always treated as a buffoon, that came out of the blue.

The Old Etonian must mastermind Britain’s complicated EU divorce. The role involves detailed negotiations with 27 European counterparts, a major test for Mr Johnson’s notoriously short attention span.

He is likely to face some awkward meetings with world leaders, including US presidential front-runner Hillary Clinton, who he called “a sadistic nurse in a mental hospital”.
