A Philadelphia-based thinktank, the Middle East Forum (MEF), acknowledges it has spent about $60,000 (£47,000) on Robinsons legal fees and demonstrations staged in London earlier this year.

A US tech billionaire, Robert Shillman, financed a fellowship that helped pay for Robinson to be employed in 2017 by a rightwing Canadian media website, the Rebel Media, on a salary of about £5,000 a month.
A small Australian rightwing group, Australian Liberty Alliance, says it has helped fund Robinson, but did not disclose how much.
A New York City-based thinktank, the Gatestone Institute, has published a succession of articles supporting Robinsons cause.

Writing for The Independent, he said American anti-Islam commentator Pamela Gellar had provided him financial support and the alt-right website Breitbart lobbied Donald Trumps ambassador for international religious freedom lobbied the British government over Robinsons case.
