The Gorton & Denton constituency at the heart of the by-election battle encapsulates many concerns about the wider divides in Britain.
Social and demographic data lays bare how the seat is sharply split on ethnicity, religion and deprivation lines.
It was comfortably secured by Labour in 2024, as Keir Starmer secured his huge landslide nationally.
But the government’s plunging popularity has left the dynamics of the local area very much under the microscope.
The constituency, south east of the city centre, has lagged significantly behind the rest of Manchester in terms of improvements in wealth.

And a recent profile by political scientist Professor Rob Ford points to the stark differences between the west and east sides.
In the west, the four wards closest to the centre of Manchester have significant Muslim populations, at 40 per cent.
Some 42 per cent are either a university graduate or a current university student.
Even though the Greens have not historically performed well in the seat, these are some of the kinds of voters being most intensively targeted by Zack Polanski’s party.
The Greens have been openly playing on the strength of feeling about the Gaza war, accusing Labour of betraying Palestinians.
Meanwhile, deeper into the suburbs to the east the picture is dramatically different.
The three wards here are on average 83 per cent white, 86 per cent UK born, and 30 per cent in routine or semi-routine jobs, according to Prof Ford.
Those are the sorts of areas that would appear fertile ground for Reform, which has campaigned hard on immigration and identity issues.
Social and demographic data lays bare how the seat is sharply split on ethnicity, religion and deprivation lines.
However, the two ‘wings’ of the constituency are not evenly matched.
At council elections in 2024 the four wards closest to Manchester had 55,000 registered electors in them.
By contrast there were only 26,000 in the three Eastern wards – leaving Reform potentially needing Labour and the Greens to split the left-wing support in order to emerge victorious.
