The 20th anniversary of the Good Friday Agreement has raised some tricky questions, not least why we haven’t had a functioning assembly for the last 15 months.

If, as we were told this week, the Good Friday Agreement (GFA) was wonderful, why are a quarter of a million people here waiting for a first hospital appointment with a consultant? If it was such an historic success, why are most of our schools bankrupt and if it represented a breakthrough, why are 370,000 people here still in poverty, including 110,000 children? Don't be silly, you say, the GFA was not about that sort of thing.

Rightly or wrongly, hope was in the air at the 20th anniversary of the Good Friday Agreement.

Just about everybody seemed to be talking about the Good Friday Agreement on Tuesday.

Over the last 15 months there has been little reason to rejoice in political terms.
