Karim Khan makes allegation in court submission while defending move to prosecute Israeli prime minister in 2024

The British government threatened to defund the international criminal court and leave the Rome statute that set it up if it pressed ahead with plans to issue an arrest warrant against Benjamin Netanyahu, the ICC’s prosecutor, has claimed.

Karim Khan made the allegation in a submission to the court defending his decision to prosecute Israel’s prime minister.

Khan does not name the individual who made the threats, saying the call on 23 April 2024 was with a British official, but reports have suggested the caller may have been the then British foreign secretary, David Cameron. Khan said the official had argued that issuing arrest warrants against Netanyahu and Yoav Gallant, the former Israeli defence minister, was disproportionate.

Khan also claimed that in April 2024 he was warned by a US official there would be disastrous consequences if he were to issue the warrants, but Khan – faced with calls to delay – insisted during the call there had been no sign the Israeli government was willing to cooperate with the ICC or change its behaviour.
