Sir - In the south east corner of the Nuffield Orthopaedic Centre in Headington has appeared an elaborately raised and, no doubt, expensive, small car park.

This is a minor addition to the extensive parking area in the centre of the site. Every 15 metres in this space there are two powerful security lights, the cost of which must be considerable. On the nights I have looked at the car park, there have been between three and six cars there. I am not sure that I want my taxes, which I willingly provide for health, to be used on five-star security for parking. And this is leaving on one side the health and environmental issues of a health institution allowing so many people to drive to its site.

Does NOC now stand for Nuffield Orthopaedic Car park?
