LONDON: Palestine has said its relations with Britain have reached a “new low” after Prime Minister Boris Johnson announced his opposition to an International Criminal Court (ICC) investigation into alleged war crimes in the Israeli-occupied territories. In a letter to the lobby group Conservative Friends of Israel, Johnson said his government had “respect (for) the independence” of the ICC but opposed the inquiry. “This investigation gives the impression of being a partial and prejudicial attack on a friend and ally of the UK’s,” he wrote. In a statement posted on its website, the Palestinian diplomatic mission in Britain said Johnson’s letter was “deeply regrettable” and “marks a low point in UK-Palestine relations and undermines the UK’s credibility on the international stage.”
