Britain's Prince Andrew has officially received court papers relating to a sexual assault lawsuit, US officials have confirmed.

The complainant, Virginia Giuffre, is seeking damages after alleging that the Duke of York sexually assaulted her, a claim he vehemently denies.

Her lawyers said earlier this month that the duke had officially been served with the papers, but his legal team disputed the claim.

The issue of whether or not Andrew had been notified about the case - known as service of proceedings - was contested during the first pre-trial hearing of the civil case last week in New York.

But it has now been confirmed the papers were served on 21 September. Prince Andrew has until 29 October to provide a response.

Ms Giuffre is suing the Queen of England's son for allegedly sexually assaulting her when she was a teenager.

She is seeking unspecified damages, but there is speculation the sum could be in the millions of dollars.
