The Survation MRP polling also explores the views of the various different voter types Labour would need for a “progressive majority”. Ashley Kirk and Jessica Elgot have the details here.

There are two MRP polls out today. In addition to the YouGov one, commissioned by Sky News and the Times (see 8.59am), the Guardian is today publishing details of a Survation one. It says progressive voters could push Reform UK into fourth place and put Labour within touching distance of a majority if tactical voting is widespread at the next election.

Andy Burnham is beginning to attract a significant number of left-leaning voters back to Labour, motivated by a desire to stop Nigel Farage, the results suggest.

The poll of more than 8,000 voters, shared with the Guardian, suggests a widespread openness to voting tactically. It also shows the prime minister’s most successful electoral strategy would be to unite the centre and left bloc of voters, while the right remains split.
