Cllr Mann said: “Public confidence in the authority is shot to pieces and the people of Caerphilly county can’t wait until 2022 to get rid of this appalling administration, which just ignores the views of residents, such as on Pontllanfraith Leisure Centre.
“I’m writing to ask you to put the authority in special measures, as has happened in the NHS in Wales, and take control of the authority for a period of time to restore public confidence in local government in Caerphilly.”
“Our Labour-led Caerphilly Council continues to deliver valued services for all our residents every day.”
The Welsh Government confirmed receipt of Cllr Mann’s Letter and said an intervention in the running of a council would be a ‘last resort’ which required conclusive evidence of statutory failings.
But a spokeswoman admitted that they were ‘disappointed’ that the investigation into the council’s chief executive, Anthony O’Sullivan, remained unresolved six years on.
“We have been clear that once the current process underway at the council has been completed, we will begin a review to consider whether the law on internal disciplinary proceedings needs to be changed,” said the spokeswoman.
Mr O’Sullivan remains on special paid leave after initially being suspended on full pay in March 2013 following allegations of misconduct.
The council has continued to pay Mr O’Sullivan ever since criminal charges levelled against him, his deputy Nigel Barnett and head of legal services Daniel Perkins, were dropped in 2015.
A council investigating and disciplinary committee has been considering the findings of the designated independent person (DIP) assigned by the Welsh Government to investigate the dispute.
Council leader Dave Poole is expected to give an update on the committee’s progress on Tuesday July 30.
