Britain said Wednesday it was investigating allegations that UK universities have cooperated with Iran on drones and other key technologies despite a legal ban.

With Russia using hundreds of Iranian-made suicide drones in Ukraine since October 2022, Prime Minister Rishi Sunak was grilled in parliament about the report by the Jewish Chronicle earlier this month.

“We take all allegations of breaches of export controls seriously and my understanding is that officials in the Department for Business and Trade are currently now investigating the allegations made in the recent press article cited,” Sunak said.

“We will not accept collaborations which compromise our national security,” he said, pointing to stepped-up controls on academic collaborations in technology.

Alicia Kearns MP, chair of the Commons Select Committee on Foreign Affairs had earlier said: “This is a horrifying collaboration, one that I fear risks breaching sanctions in place around sensitive and dual-use technologies.”

According to the Jewish Chronicle, Tehran funded researchers in Britain working on improving drone engines in a project that boosted altitude, speed, and range.

In addition to its ban on military and "dual-use" technologies being exported to Iran, the UK has recently imposed new sanctions against Iranians supplying Russia with kamikaze drones that are being used in Ukraine.

At least 11 British universities, including Cambridge, Cranfield, Glasgow and Imperial College London, were named by the Jewish Chronicle as taking part in studies with potential Iranian military applications.
