Labour made two gains in the latest council by-elections but a Ukip surge served a warning to major parties amid the latest revelations in the MPs' expenses scandal.
Liberal Democrats surrendered a Holmewood and Heath seat they had taken at North East Derbyshire District in 2008 when they failed to field a candidate.
Labour's Lee Stone easily won in a straight fight with Tories.
The second gain came at Blackburn with Darwen Borough when Mustafa Desai triumphed at Queen's Park where the previous councillor had been elected as a Lib Dem but later became independent.
Labour won another seat in the ward in the 2008 main polls.
Ukip shot from fourth place to second as Tories held on at Newchapel, Newcastle-under-Lyme Borough, Staffordshire.
Earlier in the week Liberal Democrats scored a landslide victory at Whyteleafe, Tandridge District, Surrey.
They defended a seat in a ward in which Tories have another councillor.
