Gaby Hinsliff on five things we learnt from the leaders debate...
1. Nicola Sturgeon is seriously having a moment. Her vow that, as a working class girl who'd never have made it without state education, she'd 'fight, work, vote, do whatever it takes' for free university education was one of the few genuinely standout moments - and a snap poll of viewers judged the SNP leader the top performer.
2. The Greens' Natalie Bennett is back in the running. Pilloried for her infamous 'brain fade' moment, when she got tied up in knots explaining her party's housing policy during a radio interview, she performed far more fluently this time. Which does her no harm with younger voters flirting with going Green.
3. There's literally no subject - house prices, the NHS, the economy - that Nigel Farage can't turn into a row about immigration.
4. Bennett, Sturgeon, and Plaid Cymru's Leanne Wood were all quicker and braver than the three established male leaders in challenging Farage over immigration. But is that because they're women, or because they're all from small, left-of-centre parties with nothing to lose?
5. David Cameron wants to tell you about his longterm plan; Ed Miliband wants you to know he's on your side; Nick Clegg wants to balance out the excesses of whoever wins. And if you're a teensy bit bored of hearing that already, then the election campaign is going to feel like a long six weeks...
