Wirral BC chief executive Graham Burgess is to leave the authority at the end of the year.
Mr Burgess has worked for the council since July 2012. He announced his retirement at a cabinet meeting on Thursday.
The former Blackburn with Darwen BC chief executive was originally brought into Wirral on an interim, part-time basis in 2012 as part of the council’s improvement process.
At the time, Wirral was working with an improvement board set up by LGA, following consultant Anna Klonowski’s investigation into the overcharging of care recipients and treatment of whistleblowers.
At the cabinet meeting, Mr Burgess said he had fulfilled his ambition to begin a process of transformation at the authority. “When I took up post, I said that first and foremost my role was to help shape the transformation of Wirral,” he said.
“Wirral is now a very different place to when I arrived, and I feel that now is the right time to hand over to let the next phase of this work begin.”
Mr Burgess added that he would “continue to take a strong interest in the borough’s future”.
Since taking up the role, Wirral has been named by LGA as having had the fastest turnaround of any council in the country, and has been selected as one of nine authorities to participate in the Public Service Transformation Network.
Wirral leader Phil Davies (Lab) credited Mr Burgess as being a “positive and transformational catalyst for change”.
Mr Burgess will step down on 31 December 2014. Wirral BC has not indicated who may replace him.
