DUP MP Gregory Campbell has challenged Translink over recent fare increases after discovering that 15 per cent of the Translink budget is spent on fuel whilst 65 per cent is spent on staff costs.
Last month, fares on buses and trains rose by more than three times the rate of inflation.
The increases average out as being 4.5 per cent on NI Railways, four per cent for Ulsterbus users, and 5.2 per cent on the Metrobus network.
Mr Campbell, who discovered the Translink budget figures via an Assembly Question, said the price rises come at a time “when fuel prices have been dropping”.
He also pointed out that “most public sector wages have been frozen” in recent times.
Mr Campbell said: “There needs to be a proper explanation from Translink and the department about these price increases.”
Last week, Translink announced it is to make some managers redundant following a review of senior staff and administration costs.
The public transport firm said the review would allow it to make £2m annual savings. The company said there would be no adverse effect on frontline services.
