To ask the Secretary of State for Health how many hospital-based doctors and consultants have left the NHS in each of the past five years. 
We do not collect data on the number of leavers and joiners in the national health service. Work force data are collected through the annual Department of Health medical and work force census. The census is a snapshot of data as of 30 September in the appropriate year. The information in the table shows the net increases in the number of consultants in each of the last five years.
