London mayor Sadiq Khan has called on the Government to cancel the planned state visit by Donald Trump after the US president continued to criticise his response to the London Bridge terror attack.

In a series of tweets over the weekend, Mr Trump mocked Mr Khan for saying there was "no reason to be alarmed" after the mayor said people should not be concerned by the additional police presence on the capital's streets after the attack.

On Monday the president brushed aside criticism of his original posting, tweeting: "Pathetic excuse by London Mayor Sadiq Khan who had to think fast on his 'no reason to be alarmed' statement.

"MSM (mainstream media) is working hard to sell it!"

Appearing on Channel 4 News, Mr Khan said Mr Trump was wrong about "many things" and that his state visit should not go ahead.

"I don't think we should roll out the red carpet to the president of the USA in the circumstances where his policies go against everything we stand for," he said.

"When you have a special relationship it is no different from when you have got a close mate. You stand with them in times of adversity but you call them out when they are wrong.

"There are many things about which Donald Trump is wrong."

Earlier Theresa May defended the mayor, while stopping short of directly criticising Mr Trump.

"I think Sadiq Khan is doing a good job and it's wrong to say anything else - he's doing a good job," she told reporters at an election campaign event in London.

"We're working with him, working together and that's important - central government and the London mayoralty and his officials working together to ensure we are responding to the attack."

A spokesman for Mr Khan, responding to Mr Trump's latest tweet, said: "Nothing has changed since yesterday.

"The mayor is focused on dealing with Saturday's horrific and cowardly attack and working with the police, the emergency services and the Government to keep London safe."
