A federal judge has rejected a bid by two women to join a high-profile sexual abuse lawsuit and ordered scandalous sex allegations against the Duke of York and a prominent US lawyer removed from the court record.

Former British royal Sarah Ferguson has been offered the chance to appear on Dancing with the Stars, after publicly announcing her desire to star on the US talent show.
