Analysis of tens of millions of votes cast in general elections since 1983 shows that Glasgow is the most left-wing city in the United Kingdom, while the southern coastal city of Bournemouth is the most right-wing.
Trinity Mirror's data unit spent time researching how many people in cities across the
The results illustrate a clear north-south divide. Glasgow, Liverpool, Dundee, and Manchester have been the most left-wing cities, while Bournemouth, Reading, Portsmouth, and Milton Keynes in the south of England have supported the Tories more than any other city.
On the whole, UK cities have cast more votes for Labour than the Conservatives since the 1983 election. Trinity Mirror's David Ottewell produced the graphic below to help us visualise the results.

Glasgow turned out to be the most left-wing city in the country. Prior to Labour's collapse in Scotland in last year's election, the party enjoyed high levels of support north of the border for decades. Liverpool is the second-most left-wing city.
At the other end of the scale, Bournemouth has voted Conservative more than any other UK city. This was where right-wing, anti-EU party UKIP's latest conference was held. All of the cities which have leaned towards the Tories over the past two decades or so are all located in the south of the country.
London, England's capital, has been almost equally balanced in how it has voted since 1983. Around 50.5% of votes cast in general elections by Londoners have gone to Labour.
