Staff shortages hit ambulances services across England

Ambulance services across the country are underperforming due to staff shortages, Labour's shadow health secretary said.

Freedom of Information requests by Labour have revealed that one in ten paramedic posts are empty - in London and East Anglia, this figure rises to one in five. The government says an extra 2,000 paramedics have been recruited since 2010.
