The Liberal Democrats are no longer a party of protest but are instead a party of government, leader Nick Clegg is set to tell their spring conference.
Victory in Eastleigh debunks "the myth" that being in coalition has undermined the party's identity and ability to fight the Tories, Mr Clegg will say.
He will also hit out at critics who wrote "political obituaries". Alan Soady reports.
