When banker Marc Grosjean discovered details of sex games scribbled on hotel notepaper in his wife’s handbag he assumed the worst.

Artemis "Mitzi" Berberi initially managed to calm him down by claiming the note describing sex acts was merely a silly game she had played with a girl friend.

But Gosjean could not rid himself of the suspicion that his wife of three years had cheated on him.

He checked her car’s Sat Nav and found it had been programmed to direct her to the same hotel named on the paper he found in her bag.

The discovery culminated in a furious row in which the 43-year-old banker spat in Ms Berberi’s face.

Grosjean, a former director at Credit Suisse and Anoa Capital, who was convicted by magistrates of both spitting and punching his wife in October, had his conviction for common assault upheld yesterday.

He was however cleared of striking Ms Berberi, head of legal affairs for Fox International Channels, after inconsistencies were found in her account.
