The amount of funding that candidates raise can play a major part in the success of their election bid. Commission records show Mr Norris has received 18 donations totalling £320,900 to date, including £100,000 from Reading football club chairman John Madejski. During the last mayoral campaign in 2000, Mr Livingstone - then an independent - was able to call on the support of celebrity backers. Chris Evans donated £200,000, while a concert raised £6,000.
