Royal Mail Group's CIO Robin Dargue is to leave the company to take up a new role at networking technology company Alcatel-Lucent.
Dargue will remain with Royal Mail for up to six months, during which time he will help with the transition to his successor. The company is currently searching for Dargue's replacement.
Dargue joined Royal Mail in November 2007 to oversee a £2bn technology modernisation project encompassing new systems, software and equipment across virtually all divisions in the Royal Mail Group.
As part of this he has overseen the introduction of 27,000 PDAs across Royal Mail Group and the implementation of the UK's largest wi-fi network. His work around the transformation project contributed to him topping the silicon.com CIO50 list of the UK's 50 most influential heads of IT in 2008.
Projects that Dargue will continue to lead before his departure include the migration of 30,000 desktop users from Lotus Notes to Microsoft's cloud-based BPOS software and the creation of an industry advisory board to promote technology innovation within the group.
Before Royal Mail, Dargue was CIO at drinks company Diageo. While there, he reshaped the company's global IS function, including introducing a common business process platform.
