I don't want Starmer to have a working majority. There are no good outcomes in the next election, but least bad might be Labour as biggest party in a hung parliament, cobbling together a coalition that has to include the SNP. I don't wan the tories back in, but I don't want a strong Starmer either. (In a fantasy world, Starmer is unseated by a pro-Palestinian candidate, Labour have to choose a new leader sharpish to try to form a govt. But that is just fantasy - Starmer might get a bloody nose and a reduced majority but he'll win his seat.
Maybe by a fluke of arithmetic, he has to court the support of the new independent MP for Islington North, a certain J Corbyn.)
