Quote:London mayor Sadiq Khan has urged Labour voters to ditch Jeremy Corbyn as leader and vote for Owen Smith in the party's leadership contest.
Writing in the Observer, Mr Khan said Mr Corbyn had "totally failed" to get his messages across in the UK's EU referendum in June.
"Why would things be different in a general election?," Mr Khan said.
Explaining his support for Mr Smith, he said the pair had agreed on the "big issues", such as opposing the Iraq War.
Labour 'suffering badly'
Mr Khan said: "Jeremy has already proved that he is unable to organise an effective team and has failed to win the trust and respect of the British people.
"Jeremy's personal ratings are the worst of any opposition leader on record and the Labour party is suffering badly as a result.
"He has lost the confidence of more than 80% of Labour's MPs in Parliament - and I am afraid we simply cannot afford to go on like this."
