The Department for Work and Pensions has appointed Mayank Prakash as director general for technology, a new title replacing the CIO role.

Former Government CIO Andy Nelson was the most recent chief information officer at DWP before he resigned in March, less than a year into the post.

As director general for technology, Prakash will be responsible for the DWP's IT services, and for ensuring that the department's technology supports "current and new digital services". DWP is responsible for the troubled Universal Credit rollout.

"I am delighted to have been asked to join DWP," Prakash said.

"This is a once-in-a-lifetime opportunity to simplify welfare by transforming one of the UK's largest IT estates to deliver easy-to-use digital services."

The DWP said that Prakash has experience in leading large-scale transformation for complex, global, multi-channel retail financial services and telecoms businesses. This includes implementing online services, mobile apps and big data analytics integrated with social platforms.

He joins the department from Morgan Stanley, where he was managing director of wealth and asset management technology delivery centres. Prior to that, he led IT, security and digital business transformation at Sage UK. He also has previous experience leading technology teams for Lucent and Avaya, where he was international IT director. He holds an MBA from Manchester Business School.

Former DWP CIO Andy Nelson was appointed into the role in February 2013, taking over from Philip Langsdale, who passed away at the end of 2012. Prior to his DWP role, Nelson was CIO across government. This followed a spell as Ministry of Justice (MoJ) CIO. The government CIO role was scrapped when he joined DWP.

Iain Duncan Smith, Secretary of State for Work and Pensions, announced the appointment of Prakash. Earlier this week the former Tory leader was forced to insist that the full business case for Universal Credit was expected to be signed off 'very shortly' by the Treasury, despite it being five months since it was submitted.
