Former Tour de France winner Bradley Wiggins faces new questions after it was repored that Britain’s most successful Olympian committed a “whereabouts failure” in May – less than three months before he won gold in Rio.

According to The Daily Mail, Wiggins received a warning. He gave 'insufficient information about his whereabouts in May. The British newspaper reported that Wiggins 'blamed the time difference and the fact it was an overnight flight' on his return home from the Tour of California in which he finished 121st.

If an athlete misses three tests in a 12-month period, he can receive a two-year ban.

"It’s bloody hard because what happens is you miss one test, they write you a letter, they ask you to explain what happened and you’ve got two weeks to put a case forward. If you ignore that and then you get another one, you end up having crisis meetings. You get a lot of support from UK Sport. They’re brilliant. They’re on the phone daily. They send you emails, reminders, they’ll put plans in place for you in terms of someone helping you with the whereabouts, so you don’t end up… well, it’s very difficult, then, to go from two to three (missed tests). And to get three within eight or nine months, there’s no excuse", Wiggins explained.

A few days ago, UK Anti-Doping expanded its inquiry into British Cycling to investigate multiple allegations of wrongdoings from Team Sky and Wiggins.
