DUBLIN'S north inner city was revealed as Ireland's dirtiest location, prompting calls for it to be cleaned up.
The area was branded a litter blackspot in the latest Irish Business Against Litter (IBAL) report.
It came last in a league of 42 places throughout the country which were surveyed.
IBAL chairman Tom Cavanagh said it was one of the worst results the organisation has seen in the past decade.
Six other towns and cities were found to be moderately littered, with Dublin city as a whole included in this group.
The remaining 35 locations were either clean to European norms or cleaner than European norms.
IBAL blamed absentee landlords and property owners, such as NAMA and Iarnrod Eireann, for contributing to the litter problem in Dublin's north inner city, which excluded O'Connell Street.
Mr Cavanagh said there are derelict buildings "whose landlords are nowhere to be seen and so cannot be held to account for the surrounding litter and dumping".
