From the story here:
But it was not at all clear that a change of leadership could help resolve the arguments over Brexit, as the withdrawal is known, that are tearing apart the Conservatives, or that it would leave the government any more prepared to negotiate with the European Union. ... The cabinet is divided between those who want a clean break with the European Union — so-called hard Brexit — and those who hope for a softer departure to cushion the economy. When a consensus started to emerge from the cabinet, ahead of a speech last month by Mrs. May in Florence, Mr. Johnson, the foreign secretary, undermined it by outlining his own, more hard-line and upbeat vision of Brexit in a 4,000-word article.
