Britain, Australia, and Canada on Sunday recognised a Palestinian state in a seismic shift in decades of Western foreign policy, triggering swift Israeli anger.

Portugal was also to recognise Palestinian statehood later Sunday, as Israel came under huge international pressure over the war in Gaza triggered almost two years ago by the October 7, 2023, Hamas attack.

“Today, to revive the hope of peace for the Palestinians and Israelis, and a two-state solution, the United Kingdom formally recognises the State of Palestine,” UK Prime Minister Keir Starmer said in a message on X.

Britain and Canada became the first G7 countries to take the step, with France and other nations expected to follow at the annual UN General Assembly, which opens Monday in New York.

“Canada recognises the State of Palestine and offers our partnership in building the promise of a peaceful future for both the State of Palestine and the State of Israel,” Canadian Prime Minister Mark Carney wrote on X.

It is a watershed moment for Palestinians and their decades-long ambitions for statehood, with the most powerful Western nations having long argued it should only come as part of a negotiated peace deal with Israel.

But the move puts those countries at odds with the United States and Israel, with Israeli Prime Minister Benjamin Netanyahu reacting angrily and vowing to oppose it at the UN talks.

Calls for a Palestinian state “would endanger our existence and serve as an absurd reward for terrorism,” Netanyahu said Sunday.
