Boris Johnson has confirmed he will run for London Mayor and has resigned as shadow minister for higher education.

He announced his decision on his website this morning but said he would remain an MP and continue to represent Henley. Johnson said he had been ‘overwhelmed by the support I have received from so many people across London’.

Johnson said in a statement: ‘London is an outstandingly varied and beautiful place and it deserves a proper debate. I want to bring fresh ideas to the Capital and offer a new direction for Londoners. I believe that the mayor of London should keep things simple and direct his or her intellectual energy at the core problems that affect people’s everyday lives.

‘I look forward to announcing my detailed proposals later in the summer, should I be fortunate enough to be shortlisted by the Conservative Party. Even the greatest cities have further greatness in them. I will stand for a greater London and for putting the smile back on London’s face.'
