Letter from Karen Dunnell, dated 2 May 2007:
As National Statistician, I have been asked to reply to your question regarding what discussions the Office for National Statistics has had with Dacorum Primary Care Trust on the number of patients registered in Hemel Hempstead constituency. (135326)
I can confirm that we have had two data requests from Dacorum PCT with regards to population estimates. Other than this I am not aware of Dacorum PCT contacting ONS with regards to the number of patients registered in Hemel Hempstead constituency.
