An otherwise excellent article surely goes badly astray in the final paragraph when it claims the Democratic Unionist Party played a major part in the Northern Ireland peace process and the Good Friday Agreement (Theresa May: a PM propped up by the DUP, a party tainted with terror, News, June 11). In fact the party, rabidly led by Dr Paisley, bitterly opposed the agreement and conducted a vitriolic campaign against its Unionist supporters like David Trimble in the subsequent referendum, which endorsed it by a decisive majority.

The process by which Dr Paisley and his party were over time lured away from their intransigent stance is fascinatingly described by Jonathan Powell in his book Great Hatred, Little Room: Making Peace In Northern Ireland.
