This week Sir Keir Starmer signalled he could expel left-wing Labour MPs from the party if they are openly critical of NATO. He said that under his leadership the party will show ‘unshakeable support’ for the alliance, and he will continue to call out any ‘false equivalence between Russian aggression in Ukraine and the acts of NATO’. Asked directly if he would expel MPs who are anti-NATO, Sir Keir said, ’Yes, these are principles that are absolutely at the root of the Labour Party. I'm determined that our party will face the electorate and not the sort of internal machinations and arguments that we have had too much of in the past.’ In February he told eleven Labour MPs to withdraw their signatures from a ‘Stop the War’ letter which criticised NATO.
