LONDON — Half the positions on Theresa May’s all-powerful Brexit cabinet committee have been given to hard-line Euroskeptics, a leaked government list obtained by POLITICO reveals in further evidence that the U.K. is heading toward a hard exit from the European Union.

Every senior cabinet minister who campaigned for a vote to leave the EU has been given a place on the committee, which acts as the government’s ultimate decision-making body on Brexit.

The three leading Brexiteers — Boris Johnson, David Davis and Liam Fox — are included, as expected. But Theresa May has also given positions to International Development Secretary Priti Patel, Transport Secretary Chris Grayling and Environment Secretary Andrea Leadsom — all prominent members of the Leave campaign.

The remainder of the “European Union Exit and Trade Committee” is filled by cabinet ministers who supported a vote to remain and are likely to favor a “soft” exit from the EU. Alongside the prime minister — who chairs the committee — Chancellor Philip Hammond, Home Secretary Amber Rudd and Business Secretary Greg Clark are named.

May has also given a spot to her long-time friend and ally Damian Green, the work and pensions secretary, and Conservative Party Chairman Patrick McLoughlin, who sits in the cabinet as the chancellor of the duchy of Lancaster. Both supported a vote to Remain.

In a controversial move, the secretaries of state for Scotland, Wales and Northern Ireland are not given permanent positions around the decision-making table. Instead they attend “as required” by the prime minister.

The makeup of the committee has, until now, been kept secret, with Downing Street refusing to name the ministers chosen by the prime minister.

The cabinet committee has met at least three times already, a senior government aide said, but the details of its discussions and membership have been kept closely under wraps. The first meeting was on July 26.

Cabinet committees are smaller “sub committees” of the full cabinet, usually designed to streamline policy areas which cut across a number of government departments, such as tackling extremism.

According to the Cabinet Office manual, which sets out the rules of government, “cabinet committee decisions have the same authority as [full] cabinet decisions.”

May's decision to use a cabinet committee — which is at least half the size of a full cabinet — to run Brexit suggests she intends to control the process tightly. The committee's remit includes overseeing Britain's negotiations with the EU and formulating wider trade policy.
