– Conservative Party co-chairman Baroness Warsi
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.
The newly re-elected London Mayor Boris Johnson thanked the people of London for giving him a "second mandate" as he was sworn in at City Hall after defeating Ken Livingstone.
