Ms Taylor confirmed Mr Towill emailed her on Monday to say he would stand as a Reform UK candidate on May 1 and had switched parties.
She said it was a big disappointment but that Mr Towill would remain a good friend.
Ms Taylor said: “It is very sad that Kevin has made this decision as he’s been a real stalwart for us.
“I will continue to treat him as a good friend and he still has a lot of friends in the party.”
