The ban on smoking in pubs and restaurants in Ireland, due to be enforced from this month, has been delayed until the spring after legal wrangling designed to ensure the new law is watertight when introduced. The Irish Government's lawyers are in negotiations with the European Commission, over a grey area concerning the language used in the forthcoming bill to define a "dwelling", which will be exempt from the ban. Consequently, the imposition of the prohibition has been set back until at least the end of February.
