The latest batch of opinion polls suggest the increasingly hard-fought election campaign has done little to sway voters.
Will the surveys' results be repeated at the polling stations?
Labour remain on course for a strong win, with Conservative support dipping slightly in the Lib Dems' favour.
Three polls published on Sunday give Labour a vote share of between 36%-39%.
The surveys put the Tories on between 31%-33%, with the Lib Dems between 23%-22% - with one poll suggesting their support is up 5%.
The CommunicateResearch poll for the Independent on Sunday will make the happiest reading for the Lib Dems, putting them on 23% and the Tories down 4% on 31%.
Papers show hands
However, - a YouGov poll for the Sunday Times suggests the Lib Dems' support, along with the Conservatives', is unchanged.
YouGov put Labour on 36%, with the Tories on 33% and the Lib Dems on 23%.
SUNDAY PAPERS' SUPPORT
Labour: People, Sunday Mirror, Observer, News of the World
Conservative: Sunday Times, Sunday Express
Lib Dems: Independent on Sunday
An ICM poll for the Sunday Telegraph puts Labour on 39%, the Conservatives on 31%, and the Lib Dems on 22%.
A Sunday Mirror/Observer MORI poll puts the Labour lead on 3%, but says less than 25% of Labour voters want Tony Blair to serve a full third term, as he has pledged, if re-elected.
It says the voting intentions of those certain to vote are 36% Labour, 33% Conservative and 22% Liberal Democrat.
Meanwhile, the last Sunday newspapers before Thursday's election have shown their political hands, with most backing Labour.
The News of the World followed its sister daily, the Sun, in declaring support for Tony Blair.
The People, Sunday Mirror and Observer also back Blair, while the Independent on Sunday supports the Lib Dems and the Sunday Express and Sunday Times come out for the Tories.
