Dignitas, the Swiss assisted-suicide organisation, has been ordered to move out of its housing block headquarters.

Other tenants, all residing in Zurich's 84 Gertrudstra├če building, said they regularly encountered propped up corpses in the lift. The housing block is said to smell of death.

The petition to evict Dignitas - which has occupied a flat on the fourth floor for nine years, claiming 700 lives - was organised by 55-year-old resident Gloria Sonny. She said she suffered nightmares that she would be forced into one of the 'death flats' and forced to drink the fatal cocktail.

Speaking through his lawyer, the general secretary of Dignitas, Ludwig Minelli, said that he was searching for new quarters and that he would consider setting up in a caravan, so giving Dignitas the freedom to move around.
