Election 2015 – who’s talking politics?

In the run up to the UK 2015 General Election, the music quiz presents the major players for you to decide who to vote for. As ever I’ve tried to be impartial but I have weighted the contest toward the main three parties i.e. they get two quotes each

So. Who are these quotes coming from and which party do they represent

(this is the second of three General Election quizzes)
