The NHS Commissioning Board has announced that Dame Barbara Hakin will step up to be its interim chief operating officer and deputy chief executive.

The announcement follows the news last week that the commissioning board had approached individuals including former NHS director general Mark Britnell in relation to the role. The current postholder Ian Dalton is leaving to be president of global health at BT Global Services.

The board said in a statement: “Later this year the board plans to advertise for a permanent replacement.

“Dame Barbara Hakin, currently the board’s national director for commissioning development, will take up the role on a temporary basis from the second half of April.”

The role will see her lead the board’s large operations directorate - which includes its four regional and 27 area teams, and is responsible for direct commissioning of some specialist and primary care. It is also responsible for assurance of the clinical commissioning groups.

Rosamond Roughton, currently the board’s director of commissioning systems and strategy, will serve as interim national director for commissioning development.

Dame Barbara was previously a GP in Bradford, a primary care trust chief executive and chief executive of NHS East Midlands strategic health authority. As national director for commissioning development, she has led development of clinical commissioning policy, and overseen the CCG authorisation process, which is due to be completed imminently.

Last month allegations resurfaced about her role as NHS East Midlands chief executive in the case of former United Lincolnshire Hospitals Trust chief executive Gary Walker. He claims she was involved in telling his trust to meet performance requirements, when he believed it could not do so because of patient safety concerns. NHS East Midlands has denied the claims and in 2009 a Department of Health-commissioned review found the allegations were unfounded.

Dame Barbara is also currently the subject of a General Medical Council complaint in relation to the United Lincs claims.
