The BBC is under pressure to reveal whether any taxpayers’ money was paid to Hamas during the making of a controversial film about Gaza.

Kemi Badenoch, the Tory leader, has demanded an inquiry into allegations of “potential collusion” with the terrorist group after it emerged that Gaza: How To Survive A Warzone was fronted by a Hamas minister’s son.

The BBC initially kept the documentary online with an added disclaimer at the start, arguing that it remained an “invaluable testament” to Palestinians’ experiences of the war.

But the corporation has since removed it from its iPlayer service while it conducts “further due diligence” with Hoyo Films, the production company.

Mrs Badenoch backed calls for the broadcaster to commission a full independent inquiry into the making of the film, as well as wider claims of “systemic BBC bias against Israel”. She also threatened to withdraw the Tories’ support for the licence fee if the BBC did not take “serious action” to prove its “true impartiality”.

It comes after The Telegraph revealed that BBC bosses are set to be grilled over the row by MPs on the Commons culture, media and sport committee. Lisa Nandy, the Culture Secretary, is also set to hold urgent talks with the corporation over the sourcing for the programme.
