Prime Minister Sir Keir Starmer is considering whether to join US President Donald Trump's Board of Peace for Gaza.
The new body is part of the White House's 20-point plan to end the war between Israel and Hamas.
It is expected to temporarily oversee the running of Gaza, manage its reconstruction, and be made up of world leaders.
UK diplomats are seeking more clarity from the US State Department on the role of the board and its members.
The Sunday Times first reported that Sir Keir had been invited to join the board.
