That brings us to the end of another busy day dominated by a leaders' debate:
- The UKIP, SNP, Green Party, Plaid Cymru and Labour leaders debated live in front of a representative audience
- Clashes between Nicola Sturgeon and Ed Miliband were the most significant moments, according to BBC Political Editor, Nick Robinson .
- The SNP leader urged her Labour counterpart to be more radical, while Mr Miliband challenged David Cameron to debate him one-to-one
- Daily Express owner Richard Desmond announced a £1m donation to UKIP , saying it was a party for "good, ordinary British people".
- Lib Dem leader Nick Clegg warned of the prospect of a "hard-line right-wing" government under a coalition between the Conservatives, UKIP and the DUP
- The Conservatives launched their Scottish manifesto warning of a "coalition of chaos" involving Labour and the SNP
- And an ex-head of the NHS said politicians of all parties were ignoring a "substantial financial problem" in the health service
