Cameron goes 'all out' for victory

David Cameron has pledged to go "all out" for a convincing Tory victory as he embarked on a gruelling final push to convince undecided voters.

The Tory leader refused to speculate on the possibility of a hung Parliament, despite polls suggesting he was not on course to secure an outright win at the ballot box on Thursday.

Mr Cameron kicked off a 24-hour battlebus tour at a rally in Scotland before stopping for fish and chips in Cumbria and visiting firefighters at their station in Carlisle.

Mr Cameron campaigned overnight, talking to bakers, fishermen and ambulance drivers in Cumbria, Lancashire, Yorkshire and Lincolnshire.

Earlier, he won a big-name celebrity endorsement when TV talent supremo Simon Cowell said the Tory leader is "the prime minister Britain needs at this time".

Answering questions from staff at the Morrisons supermarket distribution centre in Wakefield - amid the aroma of freshly-baked bread - Mr Cameron welcomed Cowell's endorsement.

After chatting to fishermen and market workers as the sun rose over Grimsby waterfront, Mr Cameron took the bus to Hucknall in Nottinghamshire, where he helped local candidate Mark Spencer deliver leaflets.

The Tory leader also visited the Sir John Sherbrooke Junior School in Calverton, Nottingham, where he spoke to pupils about the General Election.
