The general election next week will be fought across 650 constituencies with more than 3,000 politicians fighting for a seat.
Before voters head out to the polls on June 8, here is a breakdown of the key swing seat constituencies in the election 2017.
What is a swing seat?
Unlike party strongholds, marginal or swing seats are usually election wildcards because they were won by a slim majority last time.
This election could see more than 100 swing seats sway the end results in favour of either the Conservatives or the Labour Party.
With ten of the most marginal seats being won by less than one per cent in 2015, voters should expect a very tense elation battle.
The City of Chester could be a hot spot for contention after Labour MP Chris Matheson defeated Stephen Mosley by just 93 votes – a swing of 2.9 per cent in 2015.

Ealing Central and Acton could be another battle for the Tories after Labour’s Rupa Huq took the constituency from the Tories by 274 votes last time.
Four more London seats could also find themselves under new leadership after June 8, according to a YouGov poll on Queen Mary University of London.
The poll predicts that Croydon Central and Hendon could change hands from Conservative to Labour, and Kingston and Surbiton, and Twickenham could be taken by the Liberal Democrats.
But not all is lost, and Labour’s Ruth Cadbury could lose the west London constituency of Brentford and Isleworth to the Tories.
