Norwich is a city with two election battles - Labour hold Norwich South with a comfortable majority while Norwich North is one of the most marginal Tory seats in the land.

Conservative minister Chloe Smith held onto Norwich North by just 507 votes in one of the closest results of the 2017 General Election.

After Thurrock in Essex, it is the second most vulnerable Tory seat in the Anglia region which would switch to Labour on a swing of just 0.6%.

Not only is the county town of Norfolk divided by politics - it is also split on Brexit.

The Norwich City Council area was one of the few local authority districts in the Anglia region to vote to remain in the European Union in the 2016 referendum.

Academic analysis of that result for the parliamentary constituencies suggests Norwich South, which is dominated by the city centre and the University of East Anglia voted 60% to remain while Norwich North, which contains leafy suburbs outside the city boundary, voted 57% to leave.

Since the Norwich Norfolk constituency was created in 1950 it has swung back and forth between Labour and the Conservative although boundary change in recent years have seen the seat taking in more suburban areas.

Labour held the seat from 1950 until 1983 when the Conservatives took over for 14 years.

University academic Dr Ian Gibson won it back for Labour in 1997 and the Conservative won it back in a by-election in 2009 and have held it ever since.

Most of the city centre plus the university campus is in Norwich South while the northern and eastern suburbs plus the airport are in Norwich North.
