asked the Secretary of State for Social Services how many posts of senior registrar exist within the National Health Service; and if he will list the area health authorities to which those posts are allocated.

At 30 September 1978, the latest date for which such information is available, there was an establishment—in whole-time equivalents—of 2,545·2 senior registrar posts in England and Wales. I regret that information on the second part of the question is not collected centrally. However, the distribution of senior registrar posts between regions is given in the regional whole-time equivalent tables for hospital medical staff in England and Wales at 30 September 1978, a copy of which is in the Library.
