On rare occasions he took a medicine recommended by his doctor and formally permitted by the relevant authorities.
It's worth noting that the particular drug isn't tested for out of competition, so no TUE would be sought. I'm not suggesting that Wiggo did use the drug on other occasions, only that we wouldn't know about it if he did.
I think it’s a disgrace that the Russians have hacked into medical records
Agreed, but again, I'd go back to what I said about Froome - there have been no new revelations about him, suggesting that he has been fully transparent as he has claimed. Whereas the revelations about Wiggo are not only new, they contradict things he has said in the past. This isn't rumour or mud-slinging, it's a simple observation of facts. And given the history of the sport, I think it's fair to be concerned by the revelations.
Wiggins was fully permitted to use the substances he used.
True, but it's not the legality of his use that's being questioned, it's why that particular drug (a known PED) at that particular time (just before the Tour) - mainly because it follows a known pattern of use for non-medicinal reasons. Legal or not, that is disappointing.
