Sir, – Neil Addison’s narrative (Letters, September 12th) of the Irish reneging on treaty obligations ignores the historical reality of the Anglo-Irish Treaty of 1922 and subsequent events. The Statute of Westminster, which followed in 1931, empowered the Irish Free State to repeal any piece of legislation passed by the British parliament as it saw fit.

If Mr Addison and his compatriots exercised a more nuanced understanding of Anglo-Irish history, perhaps some of the current difficulties of Brexit might have been avoided. – Yours, etc,
