Barnet recorded the fifth slowest ambulance response times in London.

According to figures released by the London Ambulance Service, 56 per cent of ambulances arrived within eight minutes of being called in August, well fell short of the service’s target of 75 per cent.

Although this was a slight improvement on the previous month's figure of 54 per cent, the borough has one of the worst response times in London, which had an average of 62 per cent.

Overall, the figures have fallen dramatically since March, when the response time was at 76 per cent. They dropped to 63 per cent in April, before falling further to 58 per cent in June. 

In Harrow, 63 per cent of ambulances in August arrived within eight minutes, while Enfield recorded 61 per cent.

Andrew Dismore, London Assembly Member for Barnet and Camden, said: “Barnet is right down the bottom. There isn’t enough money, it’s underfunded. They don’t have the resources they need.

“In London, the population is going to keep growing, but instead of getting more money, it’s getting less. The mayor should be taking on the government, and saying what is going on here, is it not about time we get proper money for the ambulance service?”

A spokesman for the Mayor of London said: "We are aware of the challenges the London Ambulance Service is facing as demand for the service continues to rise year on year. We support their efforts to find more effective ways of meeting this growing need, including, where appropriate, offering clinical advice over the phone and referring people to alternative services such as local GPs and pharmacists.

"The mayor has written to the secretary of state to express his concerns about the LAS’ failure to meet national targets, and is due to meet Ann Radmore, chief executive of the London Ambulance Service to discuss plans to address current challenges."
