Sir Keir Starmer will recall his Cabinet from summer recess this week to hold talks on the humanitarian crisis in Gaza.
The Prime Minister is under pressure to follow French president Emmanuel Macron in recognising a Palestinian state as horror continues to mount over the conflict.
Sir Keir has so far resisted the calls, saying it should instead come as part of a wider peace process, with senior Labour figures saying he fears upsetting the US.
The PM is expected to use his relationship with Donald Trump to push for Washington to restart ceasefire talks when they meet in Scotland today.
But more than 200 MPs have urged him to immediately recognise a Palestinian state. Health Secretary Wes Streeting, Justice Secretary Shabana Mahmood and London mayor Sir Sadiq Khan are said to be among those urging the PM to move on the issue.
