Kent CC leader Paul Carter (Con) is to face a challenge to his leadership after six years in the role, according to local reports.
The Kent Messenger said an attempt to oust Cllr Carter from the top job will be made next month when the Conservative group holds its annual meeting
At least two former cabinet colleagues are weighing up whether to enter the contest.
Former cabinet member for highways, Nick Chard (Con), confirmed he intended to contest the leadership, saying he felt it was time for a change.
He said: “It is no secret that I want to see change in the way the Conservative administration handles itself and the way in which it is perceived both internally and externally.
“I want Kent to be regarded in the same way it was when it was under the leadership of Sandy Bruce-Lockhart.”
The council has been contacted for comment.
