Mr Paton, who denies one count of rape and claims the pair had consensual sex, alleged the woman had happily danced with him during the evening and also embraced him.

The woman insists she has no memory of the defendant.

Prosecutor Jonathan Loades told the jury after the lunchtime celebration the complainant continued drinking at The Dickens Inn, St Katherine's Dock, and met Mr Paton at The Dirty Martini, Bishopsgate.

She told the jury she regrets not catching the train opposite the bar and returning home to her long-term boyfriend. The pair continued partying at Whites strip club, Aldgate, before going to Paton's Whitechapel hotel, where they were filmed on CCTV.

"Exiting the lift she nearly falls into the flower pot. It is the Crown's case she was very drunk at this point," explained Mr Loades.

"The next thing she remembers is being in her words: 'Rocked.' She felt herself rocking backwards and forwards as Mr Paton was having sex with her.

"She did not know how he got there or what was going on and had one leg of her tights and one of her boots off.

"She pushed him off and went downstairs and bumped into a stranger, who seeing her distress call the police."
