There are 650 MPs being elected on Thursday. The results of who has won and who has lost will trickle in from the early hours of Friday morning. But of those, some are a little bit more interesting than others. Big beasts may fall. And others may arrive.
Identified below are 20 of the most interesting fights and what time to look out for them on election night. The list includes Nick Clegg's fight to hold Sheffield Hallam, Jim Murphy's battle with the SNP in East Renfrewshire and Nigel Farage's tight race in South Thanet.
Our picks are, of course, not the only seats to watch. Stephen Bush's run-down at the New Statesman and Alberto Nardelli's analysis at The Guardian are worth a look. We also have a full list of every seat in time order, where you can find your own constituency, here.
|3:00 AM||DOUGLAS ALEXANDERAs part of the SNP surge, Labour's campaign chief and shadow foreign secretary faces a humiliating defeat to the Scottish nationalist's 20-year-old Mhairi Black.||PAISLEY & RENFREWSHIRE SOUTH||LAB|
|3:00 AM||JIM MURPHYThe biggest casualty for Labour could be its Scottish leader, who, like all MPs in Scotland, is under threat from the SNP.||EAST RENFREWSHIRE||LAB|
|3:00 AM||SIMON HUGHESThe Lib Dem deputy leader should be a bright spot for the party. The London MP is the ultimate incumbent and Labour are finding him hard to shift. If he loses, the Lib Dems are in for a terrible evening.||BERMONDSEY & SOUTHWARK||LIB DEM|
|3:00 AM||LYNNE FEATHERSTONEVeteran Lib Dem and Home Office minister faces the chop. Senior London Labour figures believe her seat is "in the bag"||HORNSEY & WOOD GREEN||LIB DEM|
|3.30 AM||NICKY MORGANThe education secretary and potential modernising leadership candidate has a highly marginal seat. An Ashcroft poll has shown her narrowly clinging on, but Labour would love to take out a cabinet minister. The party that wins here, traditionally also goes on to form the government.||LOUGHBOROUGH||CON|
|4:00 AM||ALISTAIR CARMICHAELIf the Lib Dem Scottish secretary loses his seat to the SNP then Nicola Sturgeon is having a great night and Nick Clegg is not||ORKNEY & SHETLAND||LIB DEM|
|4:00 AM||VINCE CABLELib Dem business secretary should cling on, but David Cameron spent time campaigning in the south London seat in the last week of the campaign perhaps sensing an upset||TWICKENHAM||LIB DEM|
|4:00 AM||TIM FARRONThere is almost no chance Farron is losing his seat - however it's worth watching the Lib Dem leadership favourite's victory speech for clues about the future of his party.||WESTMORLAND & LONSDALE||LIB DEM|
|4:00 AM||ED MILIBANDThe Labour leader could be on the cusp of power, worth tuning in to hear what he has to say and what message he wants to take into the morning in a tussle for power.||DONCASTER NORTH||LAB|
|4.30 AM||DAVID CAMERONThe prime minister will walk it home in Oxfordshire, but could he spend the 2015 parliament as a mere backbencher? Like with Miliband, watch for the tone of his speech.||WITNEY||CON|
|4:30 AM||NICK CLEGGThis could be the result of the night. If Labour manage to decapitate the Lib Dem leader in what has been a tight race it will be a disaster for the party. His defeat would also change the dynamic of any hung parliament negotiations.||SHEFFIELD HALLAM||LIB DEM|
|4:30 AM||DOUGLAS CARSWELLUkip's first elected MP should be returning to parliament, but he may very well be the only member of Nigel Farage's 'People's Army' that makes it.||CLACTON||UKIP|
|4:30 AM||ALEX SALMOND The SNP's former leader is bidding for a return to Westminster and its pink champagne. Despite holding no formal party position he will be hard to ignore.||GORDON||LIB DEM|
|5:00 AM||DANNY ALEXANDER The Lib Dem chief secretary to the Treasury is likely to be a high profile decapitation by the SNP. He could be the new Portillo||INVERNESS, NAIRN, BADENOCH & STRATHSPEY||LIB DEM|
|5:00 AM||ESTHER MCVEY Of all the senior Tories under threat, the employment is most vulnerable. Labour would love to wipe the Conservatives out of Merseyside||WIRRAL WEST||CON|
|5:00 AM||GEORGE GALLOWAYThe firebrand Respect MP has said he will run for London mayor if he loses his Commons seat. His individual race, he claims, is being watched from "Manhattan to Mirpur to Baghdad”.||BRADFORD WEST||RESPECT|
|5:00 AM||CAROLINE LUCASThe Green's only MP will probably remain the party's only MP. Labour will have a tough time ousting the former (and future?) Green leader who remains incredibly popular locally..||BRIGHTON PAVILLION||GREEN|
|6:00 AM||NIGEL FARAGEThe Ukip leader has bet everything on winning a seat on the Kent coast. If he loses this tight three-way race his leadership of the party is over - and so might be the party itself.||SOUTH THANET||CON|
|6:00 AM||BORIS JOHNSONDepending on how the night has gone for Cameron and the Conservatives, Boris' victory speech could be the start of his Tory leadership campaign.||UXBRIDGE & RUISLIP SOUTH||CON|
|7:00 AM||CHARLES KENNEDYThe former Lib Dem leader was the only MP in the party who did not endorse the coalition with the Tories in 2010. But even that might not be enough to save him from the SNP.||ROSS, SKYE AND LOCHABER||LIB DEM|
