Bridgend council is to be run by a three-way coalition of Liberal Democrats, Conservatives and Independents, it has been announced.
Cheryl Green says the parties are putting together a programme
It follows Labour losing control of the council in Thursday's local elections.
Although the party still has the largest number of councillors, 21, it lost 18 councillors and the coalition parties together have 31 seats,
Liberal Democrat councillor Cheryl Green is set to be the new council leader and she said the three parties were now putting together a programme.
She said: "We want to ensure there are improvements in the delivery of services across the board for the people of Bridgend."
The council's former Labour leader Jeff Jones is critical of the coalition
"This is not about who is on what committee but putting local people first."
Mrs Green called her party's performance a "major breakthrough, as it was in Cardiff and Swansea".
The final make-up of the new cabinet and position of mayor and deputy mayor is expected to be decided at the annual general meeting of the council on 23 June.
One of the main election issues was a controversial plan to develop a rugby academy at the Island Farm
near the town.
The new coalition group has requested an immediate freeze on the development.
Former council leader Jeff Jones, who stepped down before the elections, said: "So much for democracy and so much for the people who said they represented a new style of politics.
"They very quickly got together in smoke-filled rooms.. This was not what the people of Bridgend voted for last Thursday."
