PA MediaThe UK will recognise a Palestinian state in September unless Israel takes "substantive steps to end the appalling situation in Gaza", Sir Keir Starmer has said.The prime minister said Israel must also meet other conditions, including agreeing to a ceasefire and allowing the United Nations to restart the supply of aid, or the UK would take the step at September's UN General Assembly.The government has previously said recognition should come as part of a peace process and at a point when it can have maximum impact.However, the PM has been under growing pressure - including from his own MPs - to act more quickly.Last week France also announced it would officially recognise a Palestinian state in September - the first of the G7 group of the world's richest countries to do so.Giving a news conference after holding an emergency cabinet meeting, Sir Keir said he was announcing the plan now because of the "intolerable situation" in Gaza and concern that "the very possibility of a two-state solution is reducing". He told reporters that the UK's goal of "a safe secure Israel alongside a viable and sovereign Palestinian state" was "under pressure like never before".The PM added that his "primary aim" was to improve the situation on the ground in Gaza, including ensuring that aid gets in.Sir Keir said the UK would recognise a Palestinian state unless the Israeli government takes steps including:Agreeing to a ceasefireCommitting to a long-term sustainable peace, reviving the prospect of a two-state solutionAllowing the UN to restart the supply of aidMaking clear there will be no annexations in the West BankMeanwhile, he said Hamas must immediately release all hostages, sign up to a ceasefire, disarm and accept that they will play no part in the government of Gaza.Follow live updates220 MPs call for Starmer to recognise Palestinian stateSign up for our Politics Essential newsletter to keep up with the inner workings of Westminster and beyond.
