East Midlands: where are we now?

In 2010, the East Midlands was a disaster for Labour. The Conservatives won with 29 seats, just 14 for Labour. The Liberal Democrats lost their seat in Chesterfield.

There are plenty of straight Labour versus Conservative battlegrounds, where the Conservatives need to hang on, or Labour need to make big gains.

- Labour has already won back one seat, taking Corby in the November 2012 by-election. Phil Sawford won with a 8,000 majority.

- Labour's key target in the region during this campaign has been Sherwood, which had a Conservative majority of just 214 in 2010.

- Broxtowe's Conservative MP and Defence Minister Anna Soubry is facing Nick Palmer, a former Labour MP.

- The Conservatives took Loughborough from Labour in 2010. Nicky Morgan, the Education Secretary, has a 3,744 majority. The Loughborough constituency has been won by the party that won the most seats since 1974 - so one to watch.

- And keep an eye on Boston and Skegness. A Conservative seat since 1997, this is also one of UKIP's strongest seats. They received 9.5% of the vote in 2010, their second highest, and they topped the polls in the 2013 County Council elections.
