Heather Mills, the former wife of Sir Paul McCartney, has been accused of "verbally abusing" an official from the International Paralympic Committee. Mills, who lost the lower half of her left leg in 1993, said on Monday she would not ski at the 2014 Sochi Paralympics after the IPC ruled her equipment had not been ratified. The IPC claims Mills went into a "wild tantrum" after being given the news and could now be fined. Her coach says there is a "vendetta" against her. Nick Hope reports.
