Campaigning on Wednesday has been dominated by business and taxation policies ahead of the much-anticipated leaders' TV debate.
- The Conservatives welcomed a letter to the Telegraph signed by 100 business leaders endorsing their economic policies.
- Labour, which released its own rival letter, pushed its proposal to force employers to limit zero-hours contracts to just 12 weeks.
- George Osborne and Ed Balls clashed again over tax, this time the 40p rate.
- The Lib Dems promised new fathers six weeks paternity leave instead of the current two but a poll suggested leader Nick Clegg could lose his Sheffield seat.
- UKIP argued against 16 and 17-year-olds being allowed to vote in any future referendum on the EU, claiming children are " brainwashed " in schools.
- Samantha Cameron, out campaigning in Kent, said her husband was "not too nervous" ahead of the leaders' debate.
- The SNP thinks Mr Cameron should be nervous. Treasury spokesman Stewart Hosie said the PM would face "a feisty first minister" - party leader Nicola Sturgeon.
