Spark chief executive Simon Moutter is parting on great terms with his No 2 executive Chris Quin with appreciation "for a job well done".
Quin has stepped down as chief executive of the company's home, mobile and business unit and will be replaced by marketing specialist Jason Paris, with Rod Snodgrass given extra responsibilities for digital focus.
Quin was the interim chief executive of Spark when he applied for the top job and missed out to Moutter, though the two are understood to have had a good working relationship.
By some accounts it was a close call. Indeed some expect Quin will return to the company one day. Quin has said he will pursue leadership opportunities elsewhere.
Moutter said the company was firmly on track "having made excellent progress across all our key programmes".
