Labour leader Keir Starmer will seek to clarify his position on the Israel-Hamas conflict in a speech Tuesday as the UK’s main opposition party continues to face internal splits over its response.

A number of senior Labour politicians have called for a total cease-fire in the past week, including London Mayor Sadiq Khan and Labour’s Scottish leader Anas Sarwar. Starmer has so far aligned Labour with the British and US governments in calling for “pauses” in the fighting rather than a complete halt. He suspended one of his MPs on Monday after comments they made at a pro-Palestine rally.
