Taiwo Owatemi, a new candidate for the Labour Party, has won Coventry North West in a tightly fought poll which saw two recounts.
Ms Owatemi polled 20918, just 208 votes more than her nearest rival Clare Golby for the Conservatives, with 20710.
Also standing in the seat held by Geoffrey Robinson for 45 years were Greg Judge for the Liberal Democrats, polling 2717, Joshua Richardson for the Brexit Party with 1956 and Stephen Gray, Greens candidate, polling 1443.
The majority margin in Coventry North-West collapsed from 8,580 to 208, as support for the Labour Party disappeared in an election dominated by Brexit.
Turnout was a healthy 64 per cent, with many Labour voters switching to other parties.
Ms Owatemi, a 27-year-old London pharmacist, told the Coventry Observer: “I believe we won because of our activists, and those conversations about everyday life we had on the doorstep, finding the Labour Party is committed to supporting people in their everyday needs.
“I currently live in Foleshill and I am looking for a house in the constituency where I will be able to move in the next month.
“Today’s result means there is going be division within our communities, Parliament needs radical change, and the struggle is going to be hard.
“I want to work with local colleges and universities, and set up a apprenticeship in my office to give someone local, who wouldn’t have political oppotrunities, the place to see what it is like to be in parliament.”
