OK some political guff incoming.
There are no longer the old classes as we know them.
Instead we have 7 distinct tribes in how we see the world. See link below to 3D political compass.

They are the Hard Left, the Centrists, the Progressives, the Young Kind Capitalists, the Somewhere, the Traditionalists and the Hard Right.
Labour have been of late driven by a combination of the Hard Left and the Progressives.
What's noticeable about the hard left is how they are so far away from all the other groups on the political compass.
This naturally limits the appeal they have to the other 6 groups.
My experience of NW small towns is they tend to have large numbers of traditionalists and somewhere. Where I live they don't like gentrification and 'the money moving in' because it destroys the idea of it 'taking a whole village to raise a child' which is essentially about the importance of communities looking after each other. There is a conflict between them and the progressives and the young kind capitalists for this reason.
It's often interpretated as xenophobia but I think it much more complex than that. I think it can at times have elements of that, but there's also this idea which is very positive and ensures the vulnerable are looked after.
We need to start looking at the positive elements here and communicating the idea that different ideas are not necessarily wrong and certainly do have value.
The people who gave been running Labour need to have a good hard look at the political compass and the new tribes if they want to assess where they went wrong and where they go from here.
