Take a look at this list of some of the "big beasts" who fell at this election. Must have an "end of an era" feel to it for those on the centre-left of UK politics.
Ed Balls
Vince Cable
Danny Alexander
Jim Murphy
Douglas Alexander
George Galloway
Margaret Curran
Cathy Jamieson
Anas Sarwar
Ed Davey
Simon Hughes
Jo Swinson
Michael Moore
Lynne Featherstone
David Laws
Charles Kennedy
Nick Clegg (held seat, resigns as leader)
Ed Miliband (held seat, resigns as leader)
Harriet Harman (held seat, resigns as deputy leader)
Nigel Farage (resigns as UKIP leader)
Esther McVey
Labour will turn to the likes of Ummuna, Lammy, Cooper etc. to form the shadow cabinet following the leadership election. The Lib Dems' rebuilding job will take multiple parliaments. Cameron will likely face more scrutiny from his eurosceptic backbenchers than anyone else during the next 5 years.
Many of the above I do not mind seeing the back of, but I'll miss several of them. Watching a shell-shocked Vince Cable realise he was finished in Twickenham was the saddest moment of the night for me.
