The 42-year-old son of the Earl of Mansfield has been cleared of raping a 16-year-old girl.
James Murray said he had a sexual relationship with the teenager over several days in June 2010 while she was staying in his house.
He told the court that he had "deep feelings of unease throughout" the relationship, but insisted it had been consensual.
A jury at Oxford Crown Court, who heard prosecution claims that Old Etonian Murray carried out the rape after getting the girl drunk on vodka, took just under an hour to clear him.
Murray said he had sex with her three times and once performed a sex act on her.
During the trial his sister, Lady Georgina, defended Murray as a "very kind and generous" person but who had an emotional intelligence "somewhere around the teenage mark".
