Up to 11 editorial jobs are under threat as the regional publisher Newsquest proposes to close its Citizen series of free weekly papers in Blackpool, Preston and Lancaster and move the operation of its Chorley edition to Blackburn.The closures are part of a plan announced last week by Newsquest, owned by the US newspaper giant Gannett, to make drastic cutbacks to its regional newspaper publishing operation in the north-west of England, including closing 11 newspapers.A number of non-editorial roles, including jobs in the ad sales team, are also understood to be at risk as the papers close.More informationhttp://www.guardian.co.uk/media/2008/dec/15/newsquest-citizen-titles-blackpool-preston-lancaster
