How popular is Andy Burnham?

Andy Burnham became leader of the Labour Party on 17th July 2026, succeeding a beleaguered Keir Starmer as Prime Minister on the 20th.

Burnham was by-election “Gold Dust” to voters. Swathes of would-be Green and even one-in-ten Reform supporters said if Burnham was on the ballot in their constituency they would reconsider their vote in Labour’s favour. Gorton and Denton, that fateful Manchester by-election which saw the Greens score a win “literally off the charts” could have gone a very different way.

Now Burnham is Labour leader and Prime Minister. Here’s how he’s doing.

This is the page for tracking attitudes to Andy Burnham. The headline boasts the latest figures compared to 60-days ago and six-months ago. The line chart tracks the numbers from all surveys we have in our database.

A break in the model — with a new smoothing process — is ordered when there’s a break in circumstance. Public opinion to Burnham as Labour leader and Prime Minister will be different to public opinion to him as a Labour politician. David Cameron saw an instantaneous shift in ratings upon becoming Prime Minister; and Keir Starmer saw a slight subsidence in negativity from the moment he too became Prime Minister. Charting those early days, and attitudes from them, are key. To smooth through significant shifts in circumstance would be misleading to readers.
