Final verdict
Overall tonight’s debate did what it said on the tin – showed us what a possible challenge to the current coalition could look like.
Granted it misses the obvious alternative options that Labour and the Lib Dems strike a deal, or the Conservatives and Ukip find enough common ground.
But for the first time voters were offered the options of what a wider coaltion could entail and where the red lines would lie with each.
It offered a bit more of a complex, gritty debate than the seven-way one last week, because attacks this time were focused left on Ed Miliband and right on Nigel Farage, not scatter-gun at Nick Clegg and David Cameron too.
Ed Miliband will be happy with the night, and he could have Nigel Farage to thank for that. The female left-leaning leaders were unable to resist the Ukip leader baiting them on immigration, housing (although that was immigration too) and defence which allowed the Labour leader a little breathing room.
It also gave him Mr Miliband the chance to lay down the gauntlet to David Cameron, an offer it is unlikely the Conservative leader will consider even for a moment.
