Nick Clegg predicted that the UK will face another General Election before Christmas if the Liberal Democrats do not form part of a coalition government following this week's poll.
The Lib Dem leader said it would be impossible for a minority government to pass key legislation without signing off controversial concessions to the SNP and Ukip.
A party statement said a second election in 2015 would be "almost inevitable" without the Lib Dems in parliament.
Everybody knows that no one will win this election – even if David Cameron and Ed Miliband won’t admit it publicly.
If they try to stagger through with a messy and unstable minority government instead of putting the country first then they will risk all the hard work and sacrifices people have made over the last five years.
The last thing Britain needs is a second election before Christmas. But that is exactly what will happen if Ed Miliband and David Cameron put their own political interest ahead of the national interest.
The only party that will ensure stability is the Liberal Democrats.
The Liberal Democrats will work with the party with the biggest mandate in the event of a hung parliament, Nick Clegg has said.
However, Mr Clegg did not specify whether this meant the party with the most number of seats or the largest share of the votes.
Asked whether he preferred to work with Labour or the Tories, Mr Clegg told BBC Radio 4: "The party which gets the biggest mandate...[it] seems to me right to give them the space and time to try and form a government."
He accused David Cameron and Nick Clegg of "preposterously charging around the country saying they're going to win an outright majority", adding that the Lib Dems want a "stable, decent and united government" after Thursday's vote.
Nick Clegg said his "epic journey" across the UK shows how much he "cares" about the country.
As he embarks on a 1,000-mile trip ahead of Thursday's election, the Liberal Democrat leader said: "It's just an illustration of how much I care for our wonderful country and want to communicate to as many people as I can that we need to remain stable and decent and united as a country, not lurch this way or that."
Amid mounting speculation about potential post-election deals, Mr Clegg insisted he had not engaged in talks with either the Conservatives or Labour, saying he was waiting for the "judgement of the British people".
Mr Clegg was boosted by a poll last night which suggested he was on course to retain his Sheffield Hallam seat despite a strong effort by Labour.
