Nick Clegg has become the least popular party leader in modern British political history, according to a poll.
YouGov research for the Sunday Times found just 13% thought the Deputy Prime Minister was doing a good job - compared to 78% who said the opposite.
The Liberal Democrat's -65% rating is even worse than Gordon Brown's -62% at the height of the credit crunch crisis in 2008.
The figures are a remarkable turnaround since the 2010 general election, when Mr Clegg had 74% approval and was hailed as the most popular leader since Churchill.
The Lib Dems descended into bitter infighting in the wake of disastrous local and European election results, with Business Secretary Vince Cable forced to deny he was part of a plot to oust the leader.
The newspaper reported that Lib Dem activists have now begun no-confidence proceedings against Mr Clegg in 190 local associations. They need to be successful in 75 to trigger a leadership contest.
