Starmer is performing reasonably well, but as per usual with lawyers he is being economical with the facts and information himself, and taking some things out of context. His letter was very quickly replied to, and it's another opportunity lost.
It's good to see an opposition leader who will at least attempt to take on the Tories, only issue for me though is he is not doing enough right now, he needs a significant hit or two since these minor skirmishes don't mean a thing. It would be good if instead of focusing on relatively small point scoring they can come up with some good alternatives to the Tory failures, show that they are a real alternative and not basically a protest group.
Starmer does need to be very careful too. Once this "unity politics" that the Tories claim to be following is over they have a lot of muck to throw at Labour and Starmer personally.
*edited to say Starmer does, instead of Starmer dies
