Labour's simmering row with Elon Musk has been reignited on the eve of Donald Trump's state visit.

Downing Street on Monday accused the tech billionaire of spreading 'dangerous and inflammatory' language, saying his rhetoric during a surprise appearance at an anti-migrant protest in London at the weekend threatened 'violence and intimidation'.

The Tesla and X owner told demonstrators at the march organised by hard-Right activist Tommy Robinson that 'violence is coming' and you either 'fight back or die', while also calling for a change in the UK government.

The Prime Minister's official spokesman said: 'The UK is a fair, tolerant and decent country. The last thing the British people want is this sort of dangerous and inflammatory language.'

He said it threatened 'violence and intimidation on our streets', adding: 'I don't think the British public will have any truck with that kind of language.'
