Dublin City Council should make public a contract in which advertising space is being exchanged for bicycles, a politician has said. The call comes as controversy continues to surround the deal struck between the local authority and outdoor advertisers, JC Decaux. Billboard sites worth an estimated €100m are being handed over by the council in return for 450 bicycles. The bikes, which will not be available for another year, will be provided free of charge to members of the public for short journeys through the city. Labour’s Sean Kenny, who is chair of the council’s transport committee, said he would like to see more transparency surrounding the deal. “I know there is commercial sensitivity but I sometimes do not buy that line. I would be in favour of the information being made available to the public,” Mr Kenny said.
