The chair of the NHS Appointments Commission is to step down at the end of his second term.
Sir William Wells will leave the commission at the end of March 2007, six years after being appointed as the organisation's first chair.
The commission's rules do not impose any limits on the number of terms a chair can serve, but the job has to be opened up to national competition after an incumbent has served two terms.
NHS Appointments Commission chief executive Roger Moore said that Sir William, who has clocked up more than 40 years experience on NHS boards, had decided that it was time to move on.
After his departure from the Appointments Commission, Sir William will take up the chairmanship of ADL, a Leeds-based provider of long-term healthcare.
The company owns and manages nine care homes in Yorkshire, the West Midlands and the South West.
