World number one Rafael Nadal has been awarded damages after the former French Sports Minister who accused him of doping was found guilty of defamation.

Roselyne Bachelot, the former minister for health and sport, alleged that when Nadal was out of action with a knee injury for seven months in 2012 it was actually because he had tested positive for a banned substance.

Nadal who has had to pull out of the ATP world tour finals in London this week with more knee trouble took action and, after the case went to court, Bachelot was ordered to pay damages of €10,000 (£8,900), which the player will donate to a French charity.
