The marketing unit of the new cross-Border tourism body should be located in the general Newry-Dundalk area, Mr John Bruton said in Carlingford, Co Louth, yesterday. At the publication of the party's discussion document on tourism, the Fine Gael leader said tourism was an area where all-Ireland co-operation was easiest. Locating that body's marketing unit in the general Louth-Down area would itself highlight the tourism potential of the cross-Border which is almost entirely unexploited, he added.
