No Israeli government delegation will be invited to a global defence exhibition in London next month because of the Gaza war, the UK has said.

"The Israeli government's decision to further escalate its military operation in Gaza is wrong," a UK government spokesperson said. "As a result, we can confirm that no Israeli government delegation will be invited to attend DSEI UK 2025."

Israel's defence ministry called the move a "deliberate and regrettable act of discrimination" and said it would be withdrawing and not setting up a national pavilion.

UK leaders have become more outspoken against Israel's conduct in Gaza, including a recent plan to expand the war and take over Gaza City.

"There must be a diplomatic solution to end this war now, with an immediate ceasefire, the return of the hostages and a surge in humanitarian aid to the people of Gaza," the UK government spokesperson said in a statement on Friday.
