Lyra McKee: Yet again, ambiguity is not an option

The murder of 29-year-old journalist Lyra McKee, in Derry on Thursday night raises so many issues, is such an affront to humanity and our democracy, that it is very difficult to offer a composed response yet that is how we must react.

That does not preclude an assertion of this Republic’s legitimacy and our peaceful relationship with Northern Ireland, one endorsed 21 years ago yesterday when the majority of people on this island voted to support Good Friday Peace Agreement.
