In yet another shake-up at the top, Robert Dyas chief executive officer Graham Coles is leaving the business - just four months after it was acquired by Theo Paphitis.
Mr Coles was already in the role when the Dragons' Den star took over the 96-strong chain of hardware shops in July, and he has now been at the helm for a year. In total, he has spent over eight years with Robert Dyas, but a statement released by the company said that he has decided to leave the business to concentrate on new non-executive positions.

Robert Dyas commercial director Phil Green will now be promoted to a new role of chief operating officer, effective from December 1, and will report to group CEO Kypros Kyprianou.

Mr Coles' departure marks the third time in two years that the retailer has lost its man at the top. His predecessor, Steve McVey, enjoyed an even shorter tenancy than Mr Coles, resigning as chief executive last December less than five months after being appointed to the role from outside the company. Mr Coles succeeded him from his existing position as finance director.

Mr McVey himself had been brought in in July 2011 to replace chief executive Steven Round, who left the firm unexpectedly in January.

Commenting on Graham Coles' departure, Mr Kyprianou said: "We all thank Graham for his invaluable contribution to the business, that has continued to outperform expectations since it was acquired by Theo Paphitis in July.

"Graham has a superb track record in the retail and leisure industries and it has been an honour and a pleasure to work with him."
