Councillor Adam Kent’s suspension came after a full council meeting on Thursday that saw the Tories team up with the Green Party, Liberal Democrats and independents to form an alliance.
The move saw Reform lose control of the county council after 12 months in charge.
But a spokesperson for the Conservative Party said: "The chairman was very clear on a number of occasions that the Conservative Party was totally opposed to the proposed arrangement at Worcestershire County Council.
"The Conservative group leader did not make our opposition clear to his fellow Worcestershire councillors and has been suspended pending investigation.
“Conservative campaign headquarters has made clear to our councillors that this arrangement must not go ahead.”
It is not yet clear how the suspension will affect the coalition.
Well, exactly!
By suspending their councillor for stopping Reform, they’re aligning themselves with fascists. I don’t like or agree with Conservatism, but it is better than fascism. The Conservatives on this council seem to have realised that and shouldn’t be punished for doing the right thing.
