Ireland's ICG has posted bigger profit for 2017 as volumes grew.

The London-listed owner of Irish Ferries, which also has feederships and ports, said net earnings were EUR 83.3m ($103m), against EUR 58.8m the year before.

Revenue grew to EUR 335.1m from EUR 325.4m.

Chairman John McGuckian said: "2017 was another successful year for the group, despite the headwinds of increased fuel costs and weaker sterling."
