Left wing politician George Galloway today made an extraordinary offer to withdraw from the contest to be London's next mayor if Labour sacks its candidate Sadiq Khan.

Galloway, the former Respect MP for Bethnal Green, called on Jeremy Corbyn to replace Khan with a "decent" candidate.

Khan's campaign was thrown into turmoil at the weekend after an aide posted a string of offensive and abusive tweets insulting women and gay men.

Shueb Salar, described as a parliamentary assistant, resigned after being suspended by Khan on Saturday.

Galloway said Labour should sack Khan.

Either he knew the character of this man, in which case he's too wicked to be the Mayor of London or he didn't know in which case he's too stupid to be the Mayor of London. They have to get rid of Khan and whoever they put up I'll support. That's quite an offer at this stage after a very long and quite expensive mayoral campaign I'm ready to stand down if Labour will put up a decent Labour candidate.

Khan declined to be interviewed by ITV News today but Labour issued a statement.

Sadiq acted immediately to suspend Shueb Salar as soon as he was made aware of these serious issues over the weekend. Shueb Salar has now resigned from his role as a junior member of Sadiq's parliamentary staff.
