This is an historic result. The greatest city in the world has re-elected a Conservative mayor.
Boris Johnson's re-election is a testament to the way he has connected with Londoners; to his modern, inclusive approach; and his clear vision for a safer, greener, more prosperous London.
In the coming weeks and months the eyes of the world will be upon the capital, as we host the Olympic and Paralympic Games and we are at the centre of celebrations for the Queen's Diamond Jubilee. In Boris, London has a mayor with the authority, presence and charisma to represent this great city on the world stage.
Boris, and the countless volunteers who gave their time and support to this campaign, can be immensely proud of what has been achieved.This is a victory for the Conservatives, a victory for a mayor who has devoted the last four years of his life to this city and, above all, a victory for London.
Boris Johnson said he would "definitively, categorically, emphatically" turn down the job of Prime Minister if it was offered to him.
So what challenges await the man tipped by many to one challenge for the leadership of the Tory party?
With defeat at the polls Ken Livingstone, a colourful political figure for over 40 years, has stepped down.
