I discovered The Irish Times thanks to a mumsnet poster and am grateful to them whoever they were. It gives a different viewpoint so I was having a look just now and found this article:

I'm on the train with a banging headache so haven't done more than skim read but it looks interesting and I'll look properly and read around later on.
