My prediction is that 2019 was a high watermark for the Conservatives, because it was a Brexit dominated election and in most seats they were the only party pushing for a 100% leave, certainly for leaving the Single Market. It became an election about does the UK leave the EU (inc Single Market) or not. The Tory gains in 2019 were mainly the leave seats. The only Labour gain was Putney a middle class strongly remain area. This Brexit election will not happen again.
Starmer is pretty bland, but that is probably a positive as poor Corbyn was pecked to death by the media, the opposition and even some of his own party. His past legacy gave them too much ammunition.
However Labour will really struggle to get a majority as they seemed to have lost Scotland for ever. This was a core heartland say in the Blair years.
Ref Stockton North - will the Labour Party back the levelling up agenda is a key issue for me. I can see it on social issues but what about economic and industrial regeneration?
