“As that happens, we, with allies, will look at the issue of recognizing a Palestinian state, including at the United Nations,” he added. “This could be one of the things that helps to make this process irreversible.”

Cameron is on a fresh tour of the Middle East to try and push a five-point plan to quell the latest war between Israel and Hamas.

The U.K. is among those continuing to argue that a two-state solution is the only viable long-term solution to the conflict. But such a proposal faces fierce resistance from Israeli Prime Minister Benjamin Netanyahu, who has called for “full Israeli security control over the entire area in the west of Jordan,” a move he made clear is “contrary to a Palestinian state.”

The U.K. government has previously said only that it will “recognize a Palestinian state at a time when it best serves the objective of peace” and has rejected calls from British lawmakers to go further.

Cameron’s five-point plan includes a push for a new international support package for Gaza; the formation of a new Palestinian government for the West Bank and Gaza; removing Hamas’ ability to attack Israel; releasing Israeli hostages held by Hamas; and the removal of “key Hamas leaders” from Gaza.
