I f Andy Burnham had hoped that good vibes would be enough to push Labour to a full recovery after the dire premiership of Sir Keir Starmer, then a new poll from YouGov has just given him a wake-up call.

Maybe it was no coincidence that Mr Burnham was at a summit on firefighting as he approaches his 100th day as prime minister on Tuesday, given YouGov ’s research should alarm him and his Downing Street operation.

It is not that the results are particularly bad – certainly not Starmer bad – it is just that they are not good either. If Siri could come up with a definition for “meh!” it would probably look like the prime minister’s ratings with the public.

Burnham has helped Labour turn around some dire poll ratings, but he still has much to prove (PA)

And the fact is that “meh” is not good enough, given that the first 100 days is meant to be a honeymoon period which represents the easiest period for a new prime minister.

Things are only going to get more difficult from here.…
