Dorries was adopting the notion that England is Britain.....again.
I don't think that is true.
I think she is ill informed, but then there are probably loads of people who wouldn't remember that the commonwealth games was in Glasgow in 2014 because I doubt that many people have much interest in the commonwealth games at all.
But she is also either poorly briefed (surely someone should have made clear in advance of her remarks that the UK hosted the last but one commonwealth games) or perhaps that she doesn't take any notice of her briefs. I suspect the latter as she keeps making these stupid claims, also confusing Rugby League and Rugby Union and thinking Channel 4 received public funding.
