Thursday night’s mass-debate will see Miliband in the centre, with Cameron on the far right.

The full line up will be: Natalie Bennett, Nick Clegg, Nigel Farage, Ed Miliband, Leanne Wood, Nicola Sturgeon, David Cameron.

While the PM has got his wish of being far from Farage and Ed, the Labour leader has lucked out in terms of aesthetics.

“Clowns to the left of him” says a Tory source.
