The information requested is not collected centrally. However, the hon. Member might want to contact the North West Ambulance Service directly to explore if these data are locally available.
The ambulance response time data that are collected, and which includes the number of emergency calls received by ambulance trusts across England and their performances against the targets set, are published annually. The latest statistical bulletin, “Ambulance Services, England, 2006-07” was published in June 2007. Copies of the bulletin are available in the Library.
