Lincolnshire County Council will be led by a coalition of Conservatives, Liberal Democrats and Independents.
The Tories saw their previous count of 60 seats drop to 36 in last Thursday’s election - three short of the number needed to form a majority.
Since then the party has been working behind the scenes to come to an agreement with the other groups to form a coalition.
Council leader Martin Hill (Con) said: “I’m delighted that we have been able to reach this agreement.
“This will give us a firm foundation for the next four years, so the council can continue to focus on the issues that matter most to local people.
“I look forward to working alongside my new colleagues. I’m sure that together we can achieve things that benefit all our local communities.”
The Lib Dems won three seats in Friday’s election, down two from the previous term. The Independent councillors who will form the coalition are expected to be revealed later today (Thursday).
Eight Lincolnshire Independents and two Independents were elected after Thursday’s vote.
The Conservatives’ majority was cut after a surge in votes for Ukip, with 16 of the party’s candidates elected.
Labour has 12 councillors, up from four.
