NHS national director for urgent and emergency care, Sarah Jane Marsh, said: “Modern, well-equipped and reliable ambulances are a vital part of emergency care and allow staff to respond quickly and safely when patients need them most.”

The government said it is committing a further £412m over the next four years to continue renewing the fleet.

Wes Streeting, Health and Social Care Secretary, said: “These new ambulances are already helping to cut response times and keep more vehicles on the road, just as the NHS is facing a tidal wave of flu and the ongoing disruption of strikes.”
