Sir, – The Irish Times coverage of Brexit is to be commended for the issues it raises and the insights it provides. I have one plea. Could your correspondents please report "Article 50" correctly? It is not "Article 50 of the Treaty of Lisbon" as is so often reported. In fact, there is no such article. The Treaty of Lisbon has only seven articles. There is, however, "Article 50 of the Treaty of European Union". This is the provision – inserted by the Treaty of Lisbon – that governs withdrawal and the one to which we should be referring. – Yours, etc,
