Or perhaps something happened in early 2015 that enabled an

Rich 80105, please repeat after me:

"I apologise for insulting the intelligence of my readership by citing a six-year-old newspaper report as if it were current. It was a mistake to think they wouldn't notice. More to the point, however, I apologise for allowing my unhealthy obsession to find fault with the present Government to distort my judgment to the extent that I didn't even notice the mistake before I committed it."
