Labour MPs have enthusiastically rallied around Andy Burnham, who is now set to become prime minister without a leadership contest in a few weeks' time.

The key reason for this is that they hope he will be able to win back voters Labour has lost both to parties on the right and the left.

For most of his premiership, Keir Starmer's strategy, shaped by his former chief of staff Morgan McSweeney, was to focus on courting those who might otherwise vote for Reform or the Conservatives.

The logic here was that others, including traditional left-wing voters and British Muslims, simply had nowhere else to go and were not a risk.

This royally backfired with a mass exodus of traditional Labour voters, and the meteoric rise of the Green Party over the past year.
