Sinn Féin has disputed the methodology of a report which suggested that a united Ireland would cost the Republic €20bn for the next 20 years.

The report, from the Institute of International and European Affairs (IIEA), revealed that the reunification of Northern Ireland and the Republic would require an increase in taxation and a significant reduction in public expenditure.
