"The British government privately threatened to defund and withdraw from the International Criminal Court if it issued arrest warrants for Israeli leaders, Middle East Eye can reveal.

David Cameron, then foreign secretary in Rishi Sunak’s Conservative government, made the threat in April 2024 in a heated phone call with Karim Khan, the British chief prosecutor of the court.

Less than a month later, Khan announced that he was seeking arrest warrants for Israeli Prime Minister Benjamin Netanyahu and his then-defence minister, Yoav Gallant, as well as for Hamas leaders Yahya Sinwar, Ismail Haniyeh and Mohammed Deif.

In a statement at the time, Khan called for his office and the court to be allowed to carry out their work with “full independence and impartiality”.

“I insist that all attempts to impede, intimidate or improperly influence the officials of this Court must cease immediately,” he said.": https://www.middleeasteye.net/news/david-cameron-threatened-withdraw-uk-icc-over-israel-war-crimes-probe
