It's Theresa May vs Boris Johnson for the Conservative Leadership

Home Secretary Theresa May and former mayor of London Boris Johnson are set to enter the race to become the next Tory leader and prime minister. 

They will declare their candidacies, setting out how much support they enjoy and how they propose to unify the party after the Brexit vote.

Theresa May will today confirm she is to stand for the premiership - as the latest polls give her a clear lead in the race against Boris Johnson to become the new Conservative Leader 

Despite campaigning for Remain, the Home Secretary will promise to take Britain out of the EU and curb the free movement of migrants.

Launching what will be a fierce leadership battle with Boris Johnson, she also promises to appoint a Cabinet Minister for Brexit who will be a Eurosceptic.
