Christine Connelly, who was responsible for the National Programme for IT, said she will be leaving the DoH at the end of the month.
Ms Connelly said: 'The DoH faces a major reorganisation of its top structures that will result in fewer director general posts. I have been reflecting on whether I would wish to go for one of those roles and decided that I will not.'
‘I have had a fascinating and challenging time in this role and I have decided that this is the right time to step back and think about what I might do next.’
NHS chief executive Sir David Nicholson wished Ms Connelly luck in future.
‘Christine has made a major contribution to the NHS, in promoting both the sharing and management of information, and as a professional with considerable experience of leading change.
‘She has tackled a very difficult set of issues around the National Programme for IT, and moved them forward,’ Sir David said.
Health secretary Andrew Lansley said: ‘Christine has brought a huge amount of experience, talent and technical knowledge to the National Programme for IT. I wish Christine the best of luck with whatever she chooses to do next.’
Ms Connelly will be temporarily replaced on 1 July by Katie Davis who previously worked for the Cabinet Office as the executive director for operational excellence in the Efficiency and Reform Group.
