Billy Joe Saunders suspended 6 months by WBO!

Not sure what being British has to do with anything to be fair. Most people in Britain haven't heard of Saunders, and most of those who have find him to be an idiot. Hard to recall a less popular world champion in his own country.

That said you're absolutely right about the drug test fail. Suing just seems like a non starter. Might as well go to a foreign country and sue when you break a law over there which wouldn't have applied in your own nation.
