Allegations of misconduct
In 2015 Anthony O'Sullivan, the chief executive and two other executives were charged with misconduct during public office. It was alleged that they specifically 'wilfully misconducted themselves in relation to securing Caerphilly County Borough Council’s approval of a remuneration package for the said council’s chief officers from which they stood to gain for themselves'.Relating to this and other failings the Welsh Assembly commissioned a special report on the council in January 2014
