Some light relief...

23% of people see a photo of Ed Miliband and think it's David Miliband and 26% of people think David Miliband is Ed Miliband.

33% of voters correctly recognise Yvette Cooper as Yvette Cooper but 20% think she's Harriet Harman.

30% of people correctly recognise Douglas Alexander as Douglas Alexander but just as many think he's Andy Burnham.

Only 25% of voters can correctly identify Jim Murphy. More voters (30%) identify him as Liam Byrne.

Ed Balls is the most recognisable member of the top Labour team. 68% correctly identify him. Only 64% correctly identify the Labour leader.

And in evidence that the Conservatives are serious about 'knowing the enemy', Conservative voters are more likely to correctly identify the Labour shadow cabinet than Labour voters.

The results come from a ComRes poll of more than 2,000 voters for The Independent.
