Keir Starmer is historically unpopular. When he entered Downing Street, his approval rating stood around +10%. Now? The Prime Minister languishes around -50%. It's the steepest drop in support for any governing party still in its infancy. 8 out of 10 people say that Britain is getting worse as a place to live under Labour's watch. One poll conducted towards the end of last year suggested that even Andrew Mountbatten-Windsor had more public confidence than Keir Starmer's government.

What on earth is going on? What explains such an instant - and decisive - turn in public mood away from a party and a Prime Minister elected in a landslide? As the Andy Burnham saga has illustrated this week, questions around Keir Starmer's authority seem a permanent feature of the news agenda. Was it always this way? Or is there something new, something unique, to Britain and British politics in 2026?

David Runciman is a professor, an author, and host of the Past Present Future podcast. He is one of Britain's leading thinkers on democracy, power and the state.
