Non-metro working class areas left still strong in

[Wiswylfen]

The vast majority of England. In Northumberland:

Labour will have done decently in the working-class parts of Berwick even at the last election, though residual Lib Dem strength will have kept the numbers down and perhaps kept the Conservatives ahead (though, then distinguishing between 'working-class areas' and 'working-class voters'...). The same goes for Alnwick. In the rest of north Northumberland Labour will have done about as well as you'd expect for the region though with some strength in the towns that have a decent share of social housing.

Heading into the Northumberland coalfield and along the coast Labour's numbers will have jumped and then gradually built until reaching their height in Ashington. We will have won Ashington by a clear margin in 2019, and a vote-share probably exceeding 60% in most of it: that Wansbeck almost fell was down to Morpeth and to a lesser extent Bedlington, it being a landslide, and yes, some decrease in our margin in Ashington.

We'll have won Blyth and lost the constituency thanks to Cramlington. In the pit villages along the Seaton Burn we will have put up a good fight and our decline there is largely thanks to newbuilds.

Killingworth and to the north of it Camperdown and Burradon will have been a similar story. Killingworth itself quite polarised, but it won't have been close in the latter two since they lack the newbuilds of the aforementioned others.

Now heading west along the Tyne, we'll have won Newburn and Throckley, done decently in Prudhoe if not have won that, won the working-class parts of Hexham and surrounding villages, and finished it off with a victory in Haltwhistle.
