Apart from the name of the local council, the city is usually known as Londonderry in official use within the UK. In the Republic of Ireland, the city and county are almost always referred to as Derry, on maps, in the media and in conversation. In April 2009, however, the Republic of Ireland's Minister for Foreign Affairs, Micheál Martin, announced that Irish passport holders who were born there could record either Derry or Londonderry as their place of birth. Whereas official road signs in the Republic use the name Derry, those in Northern Ireland bear Londonderry (sometimes abbreviated to L'derry), although some of these have been defaced with the reference to London obscured. Usage varies among local organisations, with both names being used. Examples are City of Derry Airport, City of Derry Rugby Club, Derry City FC and the Protestant Apprentice Boys of Derry, as opposed to Londonderry Port, Londonderry YMCA Rugby Club and Londonderry Chamber of Commerce. The bishopric has always remained that of Derry, both in the (Protestant, formerly-established) Church of Ireland (now combined with the bishopric of Raphoe) and in the Roman Catholic Church. Most companies within the city choose local area names such as Pennyburn, Rosemount or Foyle from the River Foyle to avoid alienating the other community. Derry~Londonderry railway station is often referred to as Waterside railway station within the city, but is called Derry/Londonderry at other stations. The council changed the name of the local government district covering the city to Derry on 7 May 1984, consequently renaming itself Derry City Council.Change of District Name (Derry) Order 1984 This did not change the name of the city, although the city is coterminous with the district, and in law the city council is also the Corporation of Londonderry or, more formally, the Mayor, Aldermen and Citizens of the City of Londonderry.Sections 7, 8 and 132 of the Local Government Act (Northern Ireland) 1972 (Eliz II 20 & 21 c.9) The form Londonderry is used for the post town by the Royal Mail; however, use of Derry will still ensure delivery.
