Theresa Mayhas been warned by eurosceptic ministers that she will face a leadership challenge if she attempts to water down Brexit.

The Prime Minister will today attempt to form a minority Government with the Democratic Unionist Party, which has repeatedly voiced opposition to a hard Brexit.

Senior Conservatives told The Telegraph that Mrs May is "on notice" and must prove she can resist pressure from Labour, the Lib Dems and the SNP to compromise over Brexit.

There was also a mounting backlash against David Davis, the Brexit Secretary, who has been accused of pushing the Prime Minister into calling a General Election. "It's his fault," one minister said.
