The Conservatives and Labour have warned the voters against a hung Parliament, as the opinion polls remain steady.
Today the Tories will use their party election broadcast to argue that a hung Parliament will lead to "behind closed doors" politics, weak and indecisive government, economic paralysis and another election within a year.
The broadcast features a spoof 'Hung Parliament Party', setting out the need for deadlock and concludes that a vote for any party other than the Conservatives would create a hung parliament.
Today's ICM/Guardian poll puts the Conservatives on 33 per cent, down two, the Dems down one on 30 per cent and Labour up two on 28 per cent.
The prime minister Gordon Brown has claimed it is "arrogant" to talk about what deals may be done if no party has an overall majority after the election.
He added that some voters will make up their minds at the last minute.
"I do find it strange that politicians, other than me, are spending their time speculating about what happens after the election," Brown said in a BBC3 interview to be transmitted tomorrow.
"I think they might be better putting their attention into putting the policies to the people before the election.
"If it's a clear result we'll accept it, if it's a different result then we've got to deal with it, but don't presume what the people are going to vote before they vote... because that would be arrogant."
Lib Dem leader Nick Clegg fuelled speculation about the makeup of any future coalition government at the weekend when he appeared to rule out keeping Brown in power if Labour come third in terms of the popular vote.
Yesterday he stressed that electoral reform is "a first step of any government of any composition".
"The way in which politicians may need to speak to each other after the general election will be shaped, and has to be shaped, entirely by two things," he said.
"Firstly, by the result of the election... and, secondly, by the priorities that each of the parties set out.
"I have tried to be quite clear that, it seems to me, that there are some circumstances which, it seems to me, will strike most people in this country as either unfair or very fair."
Tory leader David Cameron yesterday made a personal accusation against Clegg.
"He's only interested in one thing – changing our electoral system so we have a permanent hung Parliament," he said.
"He wants to hold the whole country to ransom just to get what benefits the Liberal Democrats."
