A former adviser to Donald Trump has allegedly defended Tommy Robinson as the 'backbone of this country' as he slammed 'f***ing liberal elite reporter'.

Steve Bannon was interviewed by LBC's political editor Theo Usherwood alongside Nigel Farage today.

On air Bannon said the English Defence League founder was 'a solid guy' and that 'he's got to be released from prison.'

But Mr Usherwood responded by saying: ‘But he broke the law!’

Later, the radio broadcaster tweeted an altercation that he claims happened with the former White House Chief Strategist after the segment.

He posted: 'Bannon to me off-air: "F*** you. Don't you f****** say you're calling me out. You f****** liberal elite. Tommy Robinson is the backbone of this country."'

Yesterday clashes broke out between protesters and anti-fascists as thousands of pro-Trump activists and Tommy Robinson supporters rallied in central London.

Activists attended a Welcome Trump rally earlier on today and marched from the US embassy in nine Elms to Whitehall in joint support of Trump and Tommy Robinson.

Robinson, 35, who was listed by his real name Stephen Christopher Yaxley-Lennon on court documents, was jailed for 13 months on Friday May 25 after he pleaded guilty to contempt of court and breaching the terms of a suspended sentence for a similar offence.

He filmed outside a trial subject to reporting restrictions before broadcasting it on social media.

Judge Geoffrey Marson QC told Robinson at the time: 'Everyone understands the right to freedom of speech but there are responsibilities and obligations.'

He added that if the jurors had seen his Facebook Live he would have been asked to end the trial.
