The Prime Minister was addressing MPs after his return from the peace summit in Egypt.
Recognising Palestine helped to bring about peace in Gaza, Sir Keir Starmer has told MPs.
Addressing MPs after his return from the peace summit in Egypt, the Prime Minister said the UK had been in a position to work “behind the scenes” for a ceasefire “precisely because of the approach this Government takes”.
He said: “That does include our decision to recognise the state of Palestine.
“Because this move, taken alongside our allies France, Canada, Australia and others, helped lead to the historic New York declaration, where for the first time the entire Arab League condemned the atrocities of October 7, urged Hamas to disarm and, crucially, demanded that they end their rule in Gaza.”
But Sir Keir also stressed that the peace deal signed on Monday belonged to US President Donald Trump.
He said: “This is his deal.”
