Election 2015: Party leaders rally troops as fight for Number 10 nears end

The party leaders are giving their final speeches and issuing their final promises with less than 24 hours to go before voting opens in the general election.

David Cameron will be campaigning in Carlisle and the North West as he hopes to return to Number 10 after the historic vote on 7 May. The Tory leader hit the airwaves on 6 May when he appeared on the BBC Radio 4's Today programme.

The prime minister stressed that, despite the opinion polls indicating a hung parliament, he was still fighting for a Conservative majority in the House of Commons. Cameron warned the alternative would be a "weak Labour government propped up by the SNP".

The comments come after The Telegraph reported Cameron would attempt to maintain a minority government after the election and plan to push through a Queen's Speech.

Clegg's tour climaxes

Nick Clegg, meanwhile, is finishing his 1,000-mile trip of the country from Land's End to John O'Groats.

The deputy prime minister hopes to drum up some last-minute support for the Liberal Democrats in his party's Scottish seats, including East Dunbartonshire.

Clegg could play kingmaker after the election and the Liberal Democrat leader has outlined numerous "red lines" for his party to enter into a coalition ahead of the election result.

In particular, he has said Labour or the Conservatives will have to commit to an extra £8bn ($12bn) per year of NHS funding by the end of the next parliament.

Clegg has also declared the parties must also promise to raise the education budget in England to more than £55m.

Miliband lays down "red line"

Elsewhere, Ed Miliband will be taking the Labour fight north as he attends a rally in Leeds later on 6 May.

The leader of the opposition is expected to lay down a "red line" of his own – that the Liberal Democrats must commit to scrapping the non-dom tax status.

"Let me be clear: any government I lead after this election will abolish the non-dom rule," he will say.

"The next Labour government will do what no government has done for 200 years. We will replace the non-dom rule with a clear principle: anyone permanently resident in the UK will pay tax in the same way.

"And only Labour will do this. We have come to expect David Cameron and Nigel Farage defending the richest and most powerful. But it is extraordinary that Clegg is defending the non-dom rule too."

Farage rallies to Ramsgate

Finally, Nigel Farage will be hoping to win over the voters of South Thanet when he campaigns in Ramsgate.

The Ukip leader is two points behind the Tory candidate for the Kent seat (32% vs 34%), according to the latest poll from Lord Ashcroft.

But the research, conducted in April, revealed Farage's team was dominating the so-called "ground game" in the constituency, with a contact rate of 89%.

In addition, the survey from the former deputy chairman of the Conservatives did not name the candidates in South Thanet. This could mean Farage's "name value" could push him over the line in the election.
