Councillor David Wilkinson has resigned from Worcester City Council, where he has represented the Bedwardine ward for the past seven years.
Cllr Wilkinson said he had taken the decision because he no longer lives in Worcester. He also holds a seat on neighbouring Wychavon District Council, where he represents the Inkberrow ward.
Cllr Wilkinson said: “I have decided to resign from Worcester City Council following seven happy and productive years, as I no longer live in Worcester.
“I have greatly enjoyed my work for the residents of Bedwardine, serving as Chairman of the Planning Committee and as Cabinet member for Safer and Stronger Communities, and I will be sad to leave.
“I would like to take this opportunity to thank my colleagues on the Council for their co-operation, and the people of Bedwardine for their support.
“I am also grateful for the help and support I have received from Council officers over the years.
“I wish the Council all the very best in the work it does for this wonderful City.”
If Cllr Wilkinson’s resignation triggers a by-election, the poll will be held on May 4, coinciding with elections for Worcestershire County Council.
For a by-election to be called, a request has to be made in writing by two electors by midnight on Sunday March 26.
