More than 80 cross-party lawmakers and peers have written to the foreign secretary to demand that the UK impose sanctions on Israel and take further action in response to the International Court of Justice's (ICJ) advisory opinion on Tel Aviv’s occupation of the Occupied Palestinian Territory (OPT).
"We write ahead of the second anniversary of the International Court of Justice's (ICJ's) landmark Advisory Opinion on Israel's occupation of Palestinian territories, issued on July 19, 2024."
"We urge the government to impose sanctions and other concrete measures to uphold its legal obligations under this ruling and wider international law," the parliamentarians wrote in the letter addressed to Foreign Secretary Yvette Cooper.
It said the ICJ found Israel's continued presence in the OPT to be unlawful and called for it to end its presence "as rapidly as possible" while ceasing all new settlement activity.
It argues that two years later, Israel has failed to comply with the ruling and has instead expanded its actions in Gaza and the occupied West Bank.
"These examples underline how, without much bolder action, the Israeli Government will continue to simply ignore the words of condemnation from political leaders and governments and deepen its illegal occupation," it said.
Citing the ICJ's advisory opinion, the letter states, "All States have an obligation not to recognise this illegal situation and 'not to render aid or assistance in maintaining the situation created by Israel's illegal presence in the Occupied Palestinian Territory'."
The parliamentarians said the UK has legal and moral responsibilities under the ruling but has yet to formally respond or implement the measures they believe are required.
"We are clear that international law cannot be applied selectively. The government must apply the same principles to Israel's unlawful occupation as it does elsewhere," it said.
The letter urges the government to ban trade with illegal Israeli settlements, sanction individuals and entities linked to the occupation, suspend the UK-Israel trade agreement, and end all arms transfers to Israel, including F-35 components.
"If the government wants to show that its stated commitment to international law and human rights is more than words, then it must act decisively and without further delay," it added.
Since a ceasefire took effect on October 10, 2025, Israel has killed at least 1,108 Palestinians and wounded 3,578, according to Gaza’s health ministry.
Israel has killed more than 73,000 Palestinians and wounded over 173,000 since October 2023 in a genocide that has also caused widespread destruction affecting 90 percent of civilian infrastructure in Gaza.
