Jonathan Martin: “Donald Trump and Keir Starmer will never be linked in the same fashion as political tandems Ronald Reagan and Margaret Thatcher or Bill Clinton and Tony Blair. But the two beleaguered leaders may be remembered for leaving the same legacy — demonstrating that their countries are both in desperate need of a cleansing.”“Starmer is facing a revolt in his own party — he may be ousted by a man who’s not even in Parliament yet — and were Trump to submit to a secret confidence vote from his party’s senators, he’d likely confront a similar fate.”
