The number of registered midwives who left the national health service in the last 12 years is not collected centrally.
Since 1999 over 1,200 midwives had returned to the NHS as at March 2004.
Information on redundancies was collected for the first time last year. There were nine compulsory midwife redundancies in England in the nine months up to 31 December 2006.
This needs to be seen in the context of the last census showing there were 24,808 midwives employed in the NHS in England, an increase of 2,423 (10.8 per cent.) since 1997.
Information on how many of these posts were not then filled or replaced is not collected centrally.
