Basically, there are the makings of a Green electoral alliance here taking in a range of former Labour-voting groups (students, Muslims, young professionals, left-wing working class). 4 or 5 urban Green seats in the GE not an impossibility
For Labour the bigger problem with this is a longer term hollowing out of its support in these sorts of urban areas, which’ll be more pertinent in GEs after this one where the party isn’t so invulnerable nationally due to terminal incumbent opponent
This is pretty interesting in Newcastle too, lots of anti-Labour sentiment around:
