I've known Piers Sellers family for many years and they fully understand the first 'Official' British astronaut guff that the media are spouting. That said, he's still a Sussex boy who obtained US nationality to achieve the dream because that was the only way he would get into space. An honourable action as far as I'm concerned given he wore his British heritage firmly on his sleeve during all three trips he made and has been a fantastic ambassador for NASA back in the UK since.
