The Liberal Democrats face decapitation. A poll from Survation found Nick Clegg's Sheffield Hallam seat could be snatched by Labour's candidate Oliver Coppard at the general election.
The survey, of more than 1,000 residents, found the Liberal Democrat leader was down 30% when compared to the 2010 general election.
The data showed Coppard was on 33% in the constituency (up 17%), the Liberal Democrats were on 23%, the Tories on 22%, the Greens on 12% and Ukip on 9%.
If deposed, it would send a shockwave throughout the British political landscape and lead to one important question for Liberal Democrats: who would replace Clegg?
IBTimes UK has crunched the numbers and outlined who the runners and riders are in the Liberal Democrat leadership.
But Clegg is not out of it yet, so we have weighed up his chances against Coppard.
