asked the Minister of Health what plans he has for the purchase of more stereotactic apparatus used in the treatment of Parkinson's disease and what steps he is taking to enable maximum use to be made of such machines, especially at Preston Royal Infirmary.

The decision to purchase and use stereotactic apparatus is for individual hospital authorities on the advice of their senior medical staff. At Preston Royal Infirmary the apparatus has only recently been installed and any judgment on its use would be premature.
