Tommy Robinson could make more than £1million if he is allowed to travel to the US for a trip next month making him one of the best funded figure since World War Two, campaigners say.

The English Defence League founder, whose real name is Stephen Yaxley-Lennon has been invited to Washington by congress members, just weeks after being released from prison.

He was asked by the US think tank the Middle East Forum (MEF) and the David Horowitz Freedom Centre, a right-wing Conservative foundation to address members at a closed door meeting.

The MEF said on its website that Republican Paul Gosar and six other members of Congress invited Robinson to speak to the Conservative Opportunity Society.

Robinson, 35, remains on bail after being charged with contempt of court and has a string of previous criminal convictions.

It is unclear whether Robinson will be allowed to enter the US due to his convictions and he is awaiting to see if authorities will grant his visa for the event which is scheduled on November 14.

This week Robinson was expected to face a hearing on allegations he broke reporting restrictions by broadcasting on social media from outside Leeds Crown Court during a child sex ring trial.

But despite a number of criminal convictions in Britain, he has gained increasing popularity in the US.

Joe Mulhall, a senior researcher at anti-fascist campaign group Hope not Hate, told The Guardian: 'The inevitable media coverage that will surround the visit will no doubt lead to an increase in his already significant monthly donations from America.

'We believe that, should he be allowed to enter the US for this event, he stands to make in the range of £1m in donations with the potential for much more. America offers the opportunity for further large-scale investment in Lennon.'

MEF has a history of donating large sums and contributes £1.6million annually to right wing causes, including Robinson's legal fees.

David Horowitz has also been known to give thousands of pounds to anti-Muslim causes and donated £90,000 to far-right Dutch politician Geert Wilders.

Robinson's former assistants claimed he had received a 'massive payday' and earned hundreds of thousands of pounds in donations after being jailed for contempt in May.

Hope Not Hate fear the donations Robinson will receive could fund a potential tour of the UK which could cause tension.
