Britain's opposition parties are pressing the Conservative government to publish legal advice on Israel's adherence to international humanitarian law amidst the Gaza conflict.

The call for transparency follows an Israeli airstrike that resulted in the death of seven aid workers, including three British nationals, escalating tensions between the UK and Israel.

Labour, the Liberal Democrats, and the Scottish National Party are advocating for a cessation of arms sales to Israel if evidence shows violations of international law.

Labour's foreign affairs spokesman, David Lammy, is vocal in demanding the halt of arms trade pending the legal advice's implications on potential international law breaches.

Prime Minister Rishi Sunak acknowledges Israel's obligation to comply with international humanitarian law but remains non-committal on revealing the legal counsel sought by the government.

London Mayor Sadiq Khan joins the opposition's calls for a suspension of arms exports to Israel amid the controversy.
