AMBULANCE trusts are at the sharp edge of a service that is under record pressure, GMB warned, after figures today revealed a “mass exodus” of workers.

A Liberal Democrat freedom of information request to all ambulance trusts showed the number of people leaving services rose by more than 50 per cent from 4,609 in 2019-20 to 6,968 in 2022-23.

GMB national secretary Rachel Harrison said: “GMB has long warned recruitment and retention pressures in ambulance services are at a critical point. The stark fact is that patients’ lives are at risk.
