The surprise story tomorrow night will be the Liberal Democrats.
Liberal Democrat Leader Nick Clegg praised tireless work from activists to deliver a record breaking campaign and reminded voters they faced the "biggest political decision of their lives" on Polling Day.
"We were written off at the beginning of this campaign - yet when the polls close tomorrow night, we will be the surprise story of the election".
"We are going to do so much better than anybody thinks. I've seen it for myself in seats across the country these last few weeks.
"There's a momentum building behind our candidates in those seats where we are there in numbers, getting our message across loudly and proudly."
With the polls neck-and-neck and no party likely to hold a majority in parliament, voters face the prospect of a new government lurching to the extreme left, the extreme right, or breaking up the country unless they vote Liberal Democrat to anchor Britain to the centre ground.
Nick has visited 54 constituencies and travelled 8,367 miles - the equivalent of the length of the Nile and Amazon rivers combined together - since the end of March.
And he praised the hard work of campaigners in seats from South West England to North East Scotland, who have:
Delivered more than 50m leaflets
Knocked on more than 4m doors
Put up more than 30,000 stakeboards
Made tens of thousands of phone calls
Lib Dems also won the digital campaign reaching two million targeted voters through social media with 57 per cent of voters tweeting positively about Nick during the BBC's Question Time debate last week.
"We are getting our message across and, where we are, we are going to win.
"So we are not going to listen to our critics and those who write us off.
"They have been wrong about us before and they are wrong about us now.
"In seats the length and breadth of the country - from Land's End to John O'Groats - we can and will win.
"We will win against Labour. We will win against the Conservatives. And we will win against the SNP."
