Except for one stint in the 1980s - the Thurrock seat in south Essex had been a Labour stronghold.
But at the last election the race was so tight - two recounts were ordered. Conservative Jackie Doyle-Price just scraped in with a majority of 92 votes which is the fifth smallest majority in the UK. The turnout was just under 60 per cent.
In this report, our reporter Nashreen Issa speaks to Tyrrells Hall club members and Mike Umoren from TRUST.
There are seven candidates standing in the constituency of Thurrock:
- Tim Aker (UKIP)
- Jamie Barnes (Cannabis is Safer than Alcohol)
- Polly Billington (Labour)
- Jackie Doyle-Price (Conservative)
- Rhodri Jamieson-Ball (Liberal Democrat)
- Aba Kristilolu (All People's Party)
- Daniel Munyambu (Independent)
UKIP has been described as the 'marmite party' - even the party's leader Nigel Farage has said you either love him, or hate him.
In the South that division is as strong as anywhere. Our Political Correspondent Phil Hornby has been looking at what people across the ITV Meridian region make of UKIP:
South West Surrey is a largely rural constituency which includes the towns of Farnham, Godalming and Haslemere.
The seat has been held by the Conservatives since its creation in 1983.
It is currently represented by the Health Secretary, Jeremy Hunt. In 2010, he secured 33,605 votes - a majority of more than 16,000. The turn-out was 74.8% - one of the highest in the country:
Now for the latest in our profiles of some of the key constituencies here in the south east. And today we visit one of only two Lib Dem seats won in the last election.
The constituency consists almost entirely of the Victorian seaside town. It was a safe Tory seat until the 1990 by-election, triggered by the murder of Ian Gow. In 2010, the Liberal Democrat Stephen Lloyd, was elected as MP. He secured 24,658 votes a majority of 3,435. Turnout was 67%.

Now we have another profile of one of the key constituencies here in the south. The Constituency takes in many of the places the city is most famous for - including the Historic Dockyard, the Naval Base, Fratton Park, and Southsea seafront. Mike Hancock won the seat in 1997 as a Liberal Democrat and, in 2010, secured almost 19,000 votes, a majority of more than 5,000. The turnout was nearly 59 per cent. Mr Hancock is now an Independent.

The Southampton Itchen constituency was created in 1950 - and covers the eastern part of Southampton, the eastern docks and the city centre. It is one of only two Labour seats in the Meridian West region - and is one of the most marginal in the UK.
Labour's John Denham has been in place since 1992 - but is not standing this time. He won in 2010 with a majority of just 192 votes. The turnout then was almost 60 per cent.
The constituency of Winchester is a parliamentary seat that has been both yellow and blue in the last decade. The cathedral city is at the heart of the constituency, but it also includes surrounding places like Alresford, Chandler's Ford, Colden Common and Sutton Scotney.
The sitting MP is Conservative Steve Brine who won the seat from the Liberal Democrats in 2010 securing 27,155 votes - a majority of more than three thousand. Voting turnout was almost 76 per cent. Our correspondent Christine Alsford reports.
In tonight's constituency profile, we take a look at Dover.
Its famous port has become a major focus for the immigration debate. Little surprise then that the seat is a key target for UKIP.
Last time - in 2010 - Conservative Charlie Elphicke won it from Labour with a majority of 5,274 and the turnout was 70%.
