In his meeting with Mr Mustafa, Mr Lammy said the UK would push for peace and stability, a statement posted on X by the British Consulate in Jerusalem said.
They discussed the role of an effective Palestinian Authority in achieving peace and Mr Lammy reaffirmed support for Mr Mustafa’s government and its programme of reform, the statement added.
On Monday morning, Mr Lammy met Israeli President Isaac Herzog.
“It’s important that, whilst we are in a war, that war is conducted according to international humanitarian law,” Mr Lammy said ahead of the meeting.
“Of course I will be pressing Israeli leaders on that subject over the coming days.”
The foreign secretary also expressed frustration over a lack of British aid trucks entering Gaza “after months and months of asking”, echoing long-running complaints from aid agencies about deliveries being blocked or delayed by complex inspections imposed by the Israeli military.
He said the humanitarian situation in Gaza was “appalling” and that the UK would be providing an additional £5.5m to medical charity UK-Med to fund its work in the territory.
After the meeting, Mr Herzog said they discussed “the supreme mission of returning the hostages home to their families”.
“The foreign secretary made clear that his country will continue to work and demand for the release of all the hostages,” he said.
Mr. Herzog mentioned that he introduced Mr. Lammy to the family of Tamir Adar, who was killed on October 7, and whose body was taken into Gaza. Adar’s grandmother, Yaffa, was taken hostage and later released as part of previous deals.
He added, “The bonds between the British and Israeli peoples are as strong and robust as they are historic and impactful – especially now, in facing the challenges ahead of us.”
The Labour Party has recently faced backlash from some Muslim voters over its response to the conflict, which many consider insufficiently critical of Israel.
The new government now faces decisions on several key issues, including whether to limit or stop weapons sales to Israel due to the loss of civilian life.
When asked about the sales, Mr. Lammy said he would “look at the assessment and the legal considerations.”
