Livingstone, 66 and a Labour veteran, announced that he would not contest an election again, and said the loss was the one he most regretted during his career spanning 41 years. In his victory speech last night, Johnson, 47, vowed to fight for a "good deal for Londoners" from the government, adding he want to "deliver prosperity for everybody in this city".
Johnson regretted that his deputy mayor, Richard Barnes, had lost the election in the Ealing and Hillingdon constituency.
In a major upset, Barnes lost to Indian-origin doctor, Onkar Singh Sahota by a margin of 3,110 votes. The result of the election to the London mayorship was preceded by big wins for the Labour party across Britain, as voters punished the ruling coalition partners, Conservative and Liberal Democrats, for job losses, deep funding cuts and double-dip recession.
Indian-origin candidate for the London mayor election, Siobhan Benita, a former civil servant who contested as an independent, was described as a "surprise package of the night", after polling over 80,000 votes. She said she would again contest the election in 2016. Labour leader Ed Miliband saw the results as a vote in favour of his party, and told voters that the party was "back throughout the country on your side" after making big gains in the English, Welsh and Scottish elections.
