Cllr Terry Goodman, of Seaford Town Council, has defected from the Lib Dems to the Conservatives.
Also the Indigo Public Affairs site has some that I'd missed:
- On Fareham Borough Council Cllr Jack Englefield, elected as a Liberal Democrat in Titchfield Common Ward has left to become an independent while Cllr Nick Gregory of Fareham West Ward has defected from the Lib Dems to the Conservatives.
- On Doncaster Borough Council, Cllr Deborah Hutchinson, who was elected as an Independent in Great North Road ward, has joined the Labour Party.
- On Newport City Council Cllr Michael Brunnock has defected from Plaid Cymru to the Conservative Party. He was the sole Plaid Cymru councillor on the authority and represents Tredegar Park Ward.
- On Blaenau Gwent county borough council: The Mayor of Blaenau Gwent, Cllr Mike Bartlett, who was elected as an Independent in Llanhilleth Ward, has joined the Labour Party.
