An 'unhinged' Nigel Farage has been accused of acting 'like a giant manbaby' during a meeting with members of the US Congress.

The Reform UK leader is claimed to have 'shouted down' a Democrat politician in a 'heated exchange' about free speech this week.

Politico reported the clash occurred as Mr Farage met with members of the House of Representatives' Judiciary Committee to talk about tech during their visit to the UK.

Jamie Raskin, the top Democrat on the committee, is said to have been warning about the threat to free speech posed by Donald Trump when Mr Farage interrupted.

'We're not here to talk about Donald Trump,' Mr Farage, an ally of the US President, said, according to Mr Raskin's account of the meeting.
