Sadiq Khan has been accused of using 'desperate smear tactics' after likening his Tory opponent to Donald Trump ahead of the London mayoral election in May.
Mr Khan lumped Susan Hall in with the former -and possible future - US president and former Home Secretary Suella Braverman as he warned the vote would be 'the first test of whether the extreme right can be held back'.
The election will be the first held since the system used to choose the mayor was changed from proportional representation back to the same first-past-the-post system used in Westminster.
In an interview with the Guardian Mr Khan cited the electoral progress made by Dutch far-right leader Geert Wilders, adding: 'Here in London, one of the most diverse cities in the world, my Tory opponent in the mayoral election in May is someone who has repeatedly promoted divisive and racist content on social media, while attacking women and the Black community.'
However, his remarks were criticised by Ms Hall's campaign, with a spokesman saying: 'Susan won't take lectures on misogyny from Sadiq Khan, nor will Londoners be fooled by these desperate smear tactics after eight years of failure under his mayoralty. Londoners deserve so much better in 2024, with less crime and an end to his unfair Ulez expansion, and Susan is determined to deliver it.'
