Starmer has a fairly substantial mountain to climb to prove that Labour can govern.
It's an impossible mountain, for anyone. There's two options to try it.
First is to try to recreate it, but still as a true socialist labour party. That won't work since English people's predominantly conservative nature will keep it from power without Scotland. And I don't see Scotland ever returning to it's former self now that particular genie is out of the bottle with the self rule they've gained.
Second is to go middle of the road, which will certainly ensure failure since we don't vote that way. Although Blair's were arguably middle of the road in practice, the people didn't vote for that, they voted for Labour in a new and shiny form. After the 19th century was dominated by the middle of the road Liberals, the last time we voted for a middle of the road government was the earliest years of the 20th century with the final gasps of a near death Liberal government.
Ever since then we've voted nominally right or left with the tendency mostly towards the right. Every middle of the road manifesto attempt has failed to attract more than a minimal level of votes, whether Liberal, SDP, SDLP or Lib-Dem.
I believe this is true everywhere in Europe, the middle of the road only ever govern through PR.
