The U.K. will recognize a Palestinian state in September unless Israel agrees to a Gaza cease-fire, permits U.N. aid deliveries, and takes further steps toward lasting peace, Prime Minister Keir Starmer said Tuesday.

"He said that the UK will recognise the state of Palestine in September, before UNGA (United Nations General Assembly), unless the Israeli government takes substantive steps to end the appalling situation in Gaza, reaches a ceasefire, makes clear there will be no annexation in the West Bank, and commits to a long-term peace process that delivers a Two State Solution," the statement said.

"He reiterated that there is no equivalence between Israel and Hamas and that our demands on Hamas remain, that they must release all the hostages, sign up to a ceasefire, accept that they will play no role in the government of Gaza, and disarm."

Pressure to formally recognize Palestinian statehood has mounted since French President Emmanuel Macron announced that his country will become the first major Western power to recognize a Palestinian state in September.

More than 250 of the 650 lawmakers in the House of Commons have signed a letter urging the government to recognize a Palestinian state.
