Cycle lanes in Dublin remained blocked by illegally parked cars last year despite a pledge from the justice minister to tackle the problem.

Charlie Flanagan tweeted in June that it was unacceptable for cars to park in 24-hour cycle lanes around Dublin city. He said that he would meet with Shane Ross, the transport minister, and Eoghan Murphy, the housing and local government minister, to address it.

Mr Flanagan tweeted on June 23: “Cycle lanes must be kept clear for cyclists only. Gardaí & local authorities must act to enforce the law.”

Data compiled by Ciarán Ferrie, an architect and founding member of the campaign group I Bike Dublin, recorded 199 cars illegally parked in cycle lanes along Rathmines Road in the first six months
