The Taoiseach (/ˈtiːʃəx/; Irish pronunciation: [ˈt̪ˠiːʃəx] ( listen)) is the head of government or prime minister of Ireland. The Taoiseach is appointed by the President upon the nomination of Dáil Éireann, the lower house of the Oireachtas (parliament), and must, in order to remain in office, retain the support of a majority in the Dáil. The current Taoiseach is Enda Kenny, TD who was appointed on 9 March 2011.

The earliest known use of the term is from a 5th- or 6th-century ogham inscription in both Gaelic and British. The plural of taoiseach is taoisigh (Irish pronunciation: [t̪ˠiːʃiː] or [t̪ˠiːʃəɟ]).

Under the Constitution of Ireland, the Taoiseach must be appointed from among the members of Dáil Éireann. He is nominated by a simple majority of the chamber's members, and formally appointed to office by the President. Since the President is required to appoint whomever the Dáil nominates without the right to decline appointment, it is often said that the Taosieach is "elected" by the Dáil.

Enda Kenny (born 24 April 1951) is an Irish Fine Gael politician, and has been the Taoiseach since 2011. He has led Fine Gael since 2002. He served as Minister for Tourism and Trade from 1994 to 1997. He is also a two-term Vice President of the European People's Party.

Kenny has been a Teachta Dála (TD) for Mayo since 1975, having succeeded his father Henry Kenny. He is the longest-serving TD currently in Dáil Éireann, which makes him the incumbent Father of the Dáil.

Kenny led Fine Gael in the 2011 general election. He subsequently brokered an agreement with the Labour Party and formed a coalition government on 9 March 2011. He is Fine Gael's first Taoiseach since John Bruton from 1994 to 1997, and the first Fine Gael leader to win government in an election since Garret FitzGerald in 1982.

Enda Kenny was born in the village of Islandeady near Castlebar, County Mayo in 1951, the third child of five. He was educated locally at St. Patrick's National School in Cornanool and St. Gerald's College (De La Salle) in Castlebar. Kenny subsequently attended St Patrick's College of Education in Dublin and University College Galway. He briefly worked as a primary school teacher, and is a Gaeilgeoir.

Oliver Callan (born 27 December 1980) is an Irish vocal and performance satirist and impressionist known for featuring on Nob Nation, Green Tea and The Saturday Night Show. He rose to fame during the 2000s when his daily Nob Nation slots aired on RTÉ Radio. His Green Tea creation on RTÉ Radio 1 has been described by The Irish Times as "essentially an extended version of Nob Nation".

Nob Nation and Green Tea parody political, social and cultural personalities, with Callan performing as the characters featured on the show. His radio broadcasts have led to the release of regular podcasts, several CDs and appearances on prime time television programmes such as The Saturday Night Show on RTÉ One. He has also incurred the wrath of several politicians and the Kerry GAA star Paul Galvin for his impressions. He is well known in Ireland and the UK for skewering celebrities and politicians on radio. His acerbic wit and talent for mimicry has made him a household name, according to the Irish Independent.
