Labour were like 1% point better than 2019. The only difference was the collapse of SNP, and the collapse of the Tory nationalist vote that ran to Reform.
They campaigned on being hard on immigration and not increasing taxes to increase spending.
Keir has been quite deceptive and dropped all the policies he claimed in the leadership. He could be more right wing than Blair. So probably center right. The right wing of the party took over. Funded by business.
Corbyn, and no. He got 40% in 2017. Keir only 34% here. When the right wing turned on him, including Streeting and his Progress chums on countless occasions there isn't a lot you can do.
The right of the Labour party won't tolerate a left wing party, but the left wing are much more professional, despite treatment of Abbot, Corbyn and others joining strikes.
