Almost a quarter of all ambulances used to ferry patients to A&E departments in Northern Ireland have covered more than 150,000 miles, it has been revealed.
Of the 116-strong fleet, 42 have covered more than 100,000 miles and an SDLP MLA has claimed the high mileage could pose a risk.
John Dallat said the information came to light as the result of a written question in the Assembly.
“I tabled this question because I am aware that increasingly ambulances are involved in ‘blue light’ work, which means getting seriously ill patients to acute hospitals in Belfast in the fastest possible time.”
Mr Dallat said he had asked for further information relating to maintenance contracts.
