A Saudi millionaire has been cleared of raping a teenager after claiming he might have accidentally penetrated the 18-year-old when he tripped and fell on her.

Property developer Ehsan Abdulaziz, 46, was accused of forcing himself on the teenager as she slept off a night of drinking on the sofa of his Maida Vale flat in west London.

He had already had sex with her 24-year-old friend and said he might have slipped over on top of the younger woman.

The teenager met Abdulaziz in the exclusive Cirque le Soir nightclub in the West End on August 7 last year where she had been spending the evening with her friend, who was known to the businessman.

He invited them to join him at his £1000-per-night ($2075) table and then offered them a ride home in his Aston Martin, Southwark Crown Court heard.
