Labour has become the largest party on Ipswich Borough Council after winning three seats in the local elections.
But the council remains without any one party in overall control. Two of the Labour gains came from Conservative candidates and one from the Lib Dems.
The new council will be made up of 21 Labour members, 19 Conservatives and eight Lib Dems.
At the Lowestoft-based Waveney District Council, there was no change with the Conservatives retaining control.
Liz Harsant, leader of the Ipswich Conservative group, blamed the losses there on the recent row over the decision by Tory-controlled Suffolk County Council to pay its new chief executive £220,000.
