Boris Johnson re-elected as Mayor of London

Boris Johnson was re-elected as Mayor of London in a surprisingly narrow victory that saw him beat rival Ken Livingstone.

The Conservative polled 1,054,811 (51.53%) to the Labour's candidate's 992,273 (48.47%) following a deeply personal and bitter campaign battle that saw the two men clash furiously in public and in private.

Mr Johnson vowed to continue "fighting for a good deal for Londoners" from government as he thanked voters for giving him a "new chance".

Liberal Democrat Brian Paddick was pushed into a humiliating fourth place after polling 91,774 votes, compared to the 98,913 secured by the Greens' Jenny Jones.

Political newcomer, Independent Siobhan Benita, took fifth with 83,914.

Ukip's Lawrence James Webb polled 43,274 while the British National Party's Carlos Cortiglia came last with 28,751.

Counting, which is carried out electronically, was dogged by delays, pushing back the result back significantly on original predictions that it would be announced in the early evening.

They included a power cut at Alexandra Palace as well as the reprocessing of two mislaid batches of ballot papers in the Brent and Harrow constituency.
