London Mayor Sadiq Khan has called for a ceasefire in the ongoing conflict between Israel and Hamas, going a step beyond his Labour Party’s appeals for a humanitarian pause in fighting to allow aid into the Israeli-besieged Gaza Strip.

The apparent difference in stance between Khan and Labour leader Keir Starmer highlights disagreement and growing unrest within Britain’s main opposition party over its position on the conflict.

Labour, which polls indicate has a strong chance of forming Britain’s next government in an election expected in 2024, called this week for a pause in fighting, echoing similar calls from the US, European Union and Britain’s Conservative government.
