Bosses of a German insurance company are to be prosecuted after renting a Budapest spa and filling it with prostitutes as a reward for their best salesman.

The weekend orgy at the historic Gellert spa in Budapest made headline news when it was revealed how four-poster beds had been put up alongside the pool area.

Women at the event were given armbands to indicate whether they were there to provide food and refreshments or sex.

The prostitutes were also colour-coded with those wearing white armbands being women reserved only for the top performing salesman.
