Liverpool Wavertree: In 2005 Labour's Jane Kennedy won with a majority of 5,173. It is estimated that boundary changes have effectively eroded Labour's majority to around 3,000.
Labour are currently in the process of selecting a new candidate.
It is the Liberal Democrats' number one target seat in the North West and their candidate Colin Eldridge arguably represents their best chance of electoral success in Merseyside.
A 5% swing would see him win the seat.

Wirral West: Labour's Stephen Hesford was re-elected to the seat in 2005 with a paper-thin majority of 1,097.
But boundary changes mean that notionally Conservative Esther McVey currently has a notional "majority" of 283 votes.
Ms McVey is widely expected to win the seat which had been a Tory stronghold until 1997 when Mr Hesford won the seat.

Wirral South: Labour has just chosen public affairs expert Alison McGovern to replace Ben Chapman, who stands down at the General Election, as the party's candidate.
Chapman was re-elected with a majority of 3,724 in 2005.
Ms McGovern faces a tough challenge from barrister Jeff Clarke who is standing for the Conservatives and needs a 5% swing to take the seat from Labour.

Southport: Liberal Democrat John Pugh has held the seat since 2001, and has a majority of 3,838.
Conservative Brenda Porter needs a swing of less than 5% to win - the seat is 78th on the Tory target list.

Sefton Central (currently Crosby): Labour are yet to choose a replacement for Claire Curtis-Thomas who was re-elected in 2005.
Boundary changes have marginally eroded Labour's majority to around 5,540.
Conservative candidate Debi Jones needs a 6.6% swing to win.
Liberal Democrat candidate Richard Clein is also investing considerable amount of effort in trying to win the seat.
