The information requested is not collected centrally.
The ambulance response data that is collected centrally, and which reports on numbers of calls received and the degree to which each ambulance trust in England met the national response time targets, is contained in the annual statistical bulletin, “Ambulance Services, England”. The latest version, covering data for 2008-09, was published in June 2008. Copies have been placed in the Library, and are also available on the Information Centre for Health And Social Care's website at
www.ic.nhs.uk/pubs.
The health service in Wales is a matter for the Welsh Assembly Government.
