Another day -- another revelation about embattled Sam Uffindell

National has stood down the new Tauranga MP, following revelations about bullying at Auckland's Kings College and allegations of aggressive behaviour at Otago University.

It's now emerged he was put on notice for living in one of North Dunedin's filthiest flats.

The Otago Daily Times reports the flat -- where Uffindell and five other male students were living in 2004 -- prominently displayed a coat hook with women's underwear hanging from it.

A council health inspector visited three times while the flatmates competed for the title of Dunedin's filthiest flat, in a competition organised by a now-defunct website.

It considered the flat a health hazard, with particular concerns rat urine could spread leptospirosis, a notifiable disease.
