The Joint List called on Britain’s biggest political parties to vigorously oppose Israel’s plans to annex parts of the Palestinian occupied West Bank. The two letters, dated June 26 were penned by Hadash MK Yousef Jabareen, the head of the Joint List’s international relations committee, and were sent to the UK Conservative party leader, Prime Minister Boris Johnson, and the Labour party’s leader, Sir Keir Starmer. In the letters, the Joint List parliamentarians said the UK needed to “actively oppose” attempts by Israel to unilaterally annex territory.

“History has demonstrated the tragic consequences of illegal annexations,” the letter read. “We fear that if Britain and its European allies do not urgently act to prevent this impending annexation, our region may witness yet another major upheaval.”
