Jeremy Corbyn's brother Piers endorsed Donald Trump's right to re-tweet far-right propaganda and himself re-posted a message from a former BNP activist.

Piers Corbyn, who describes himself as a 'long rage weather and climate forecaster', posted a Twitter rant claiming the US President was only interested in publicity.

He said Mr Trump was seeking to prove politicians were more interested in attacking him rather than the content of the messages.

The older brother of the Labour leader also reposted a Tweet from Mark Collett, a former BNP activist, that attacked Theresa May as an 'Islamic appeaser'.

In his own tweet, Mr Corbyn said: 'PEOPLE! WAKE UP. MyTake is #Trump deliberately ReTweeted from someone who he knew would cause offence in order to magnify publicity and expose many politicians in front of the people for attacking the messenger (him) rather than discuss the content of the news concerned.'

The message from Mr Collett, a former chairman of the Young BNP, posted a photograph of Theresa May wearing a headscarf.

And his tweet read: 'Theresa May is an utter disgrace. She is an Islamic appeaser, multiculturalist & pawn of the internationalist bankers.

'No wonder she is angry with Donald Trump for retweeting the truth!'

Labour leader Jeremy Corbyn has condemned the President for re-posting the messages from Britain First earlier this week.

The social media posts have blown up into a huge diplomatic row between London and Washington and prompted renewed calls for Mr Trump's state visit to be cancelled.

Piers Corbyn has been a frequent source of embarrassment to his brother since he was first elected Labour leader more than two years ago.

Last year he appeared on stage alongside a notorious Holocaust denier and a leading 9/11 conspiracy theorist to give a speech claiming that man made climate change is a 'lie' promoted for profit by a global elite.

Piers Corbyn also supported Brexit and complained there was 'too much sensitivity' surrounding anti-Semitism while his brother was under pressure to kick Ken Livingstone out of Labour.
