It would be odd if a party didn't have disagreements about policy. That's why they are there - we may as well have a dictator if one person is going to decide and nobody disagrees.
I believe that Starmer has integrity, and will be a refreshing change from the current and recent cabinets. The proof of the pudding, of course, will be in the eating, but nothing he has done so far leads me to believe that he will be dishonest. He will have problems with timescale, as the economy has been ruined so the changes he wants to make will take longer than one term to implement. Meanwhile, people will be sniping from the sidelines, which must be incredibly dispiriting, but if he can rise above it and just keep on making progress the country should be a kinder and less divided place after a while.
Some of the challenges he will face will be huge. And I'm pretty sure he's well aware of that.
How much scope he has to make changes that will materially affect the various disaffected groups remains to be seen.
He has to please the wealthy, business, the financial institutions, etc, as well as the more disadvantaged.
And of course, his and Labour's critics will be watching him carefully, but - as you say, if he can weather that, there might be a glimmer of hope for a better society, eventually.
But, oh! - what a fight he has on his hands!
