London swears in eccentric new Tory mayor

An emotional Livingstone, the city's first-ever elected mayor, and in power since 2000, said the blame for his defeat must rest at his door, not Brown's. Livingstone, a staunch leftist who courted Venezuela's Hugo Chavez, frequently embarrassed his party's national leadership. Johnson's own erratic outbursts mean he may have a similar relationship with Cameron. He once caused huge offence by labelling people in some Commonwealth countries 'piccaninnies'' -- a derogatory term for black children -- and also referring to Africans as having 'watermelon smiles.'' As editor of the weekly political magazine The Spectator, Johnson survived the embarrassment of an affair with one of his writers. He called the adultery reports 'an inverted pyramid of piffle'' but was removed from the Conservative front bench when party leaders decided that was a lie."
