Tories lost five council seats in the latest local by-elections - two to Labour, one to Liberal Democrats and two to independent or other.
Labour lost one seat but comfortably held two in addition to the two gained from Conservatives.
One of the Conservative defeats at Labour's hands came at Medway Council in a poll in Rochester West ward following the resignation as a councillor of Rochester & Strood Tory MP Kelly Tolhurst.
Ms Tolhurst, first elected as MP in 2015, had a majority of 9,850 in her Commons seat at last year's general election.
She topped the poll in the Rochester West ward when she and another Tory councillor were elected in the 2015 council election.
Ukip, which won Rochester & Strood in a 2014 by-election after then MP Mark Reckless defected to the party from the Conservatives, was forced into last place, behind the Greens, in the council by-election.
Voting was: Lab 1,212, C 1,007, LD 119, Green 107, Ukip 104. The turnout was 33%.
