Theresa May has confirmed she will resign as leader of the Conservative Party on June 7.

The Prime Minister had met the leader of backbench Conservatives, Sir Graham Brady, on Friday to discuss her future after her authority was left in tatters following the backlash against her “new Brexit deal”.

Scottish Secretary David Mundell said: "I am very sorry it has come to this. Nobody could have worked harder, or shown a greater sense of public duty, in delivering the result of the EU referendum than Theresa May.

“She has my utmost respect for those endeavours, in the most challenging of circumstances, as well as her unswerving commitment to the Union. 

“As Mrs May herself acknowledges, she has, however unfairly, become an impediment to the resolution of Brexit, and was no longer being given a hearing by Parliament.

"Yesterday’s elections will surely show that delivering Brexit is now more urgent than ever, and that will fall to a new Prime Minister. 

"It's time to get on with the process of appointing one."
