Election analyst Adrian Lee has told BBC South West's Hamish Marshall that two of Plymouth's Parliamentary seats - Plymouth Moor View and Plymouth Sutton & Devonport, being defended by Labour and the Conservatives respectively - are on a "knife edge".

He added: "It's going to be interesting to see if the swings seen in the [national] exit polls are going to be seen in Devon. Also, Moor View has a demographic that would favour UKIP, but I can't really see that [a win] happening."

There were only two Liberal Democrat MPs elected in Devon in 2010 and both of them are standing for re-election in 2015.

Both Nick Harvey and Adrian Sanders are long established MPs. With Nick Harvey first elected in 1992 in North Devon.

Adrian Sanders was first elected to Torbay in 1997. So will the Liberal Democrats role in coalition add grist to their mill or see them thrown out on their ears?
