He spoke as a UK Anti-Doping Agency (UKAD) investigation continues into a package ordered by former team doctor Richard Freeman and delivered to the Briton during the 2011 Criterium du Dauphine.

It is claimed that the package contained fluimucil, a decongestant that is used to treat coughs and sore throats, but elements of the story are still unclear.

Questions also surround the true nature of three Therepeutic Use Exemptions (TUEs) Sir Bradley received to take corticosteroid triamcinolone before the Tour de France in 2011 and 2012 and the Giro d'Italia in 2013, his biggest races of all three seasons.

However, there is no direct suggestion that he broke rules.

"It's the worst thing to be accused of when you're a man of my integrity," Wiggins told Sky Sports' Soccer AM today.

"It's been horrible. 

"But fortunately there's an investigation and I obviously can't say too much because that investigation will run its course and then I'll have my say.

"There's a lot to say, and it's going to shock a few people."

Sir Bradley became the first British winner of the Tour de France in 2012.

He is also a five-time Olympic champion and eight-time medallist who bowed out following last year's Games in Rio de Janeiro as one of the greatest British athletes ever.

But his reputation has been dented by months of subsequent speculation since news of his TUEs was forced released by hacking group Fancy Bears'.

It is not clear what exactly he was referring to by his latest comments.
