Turners Auctions chief executive officer 
Graham Roberts has left the company, effective immediately.
Roberts seven-year tenure in the role ended Thursday, with chairman Michael Dossor stepping in while a successor is found.
In a brief statement to the stock exchange, the company acknowledged Robert’s contribution to the company.
The sudden departure comes after what was considered a good year for the company – which just weeks ago announced increased turnover and profit for the 2012 year.
