14 Irishmen will travel with the Lions touring squad for South Africa, with Paul O'Connell confirmed as captain.
Rob Kearney, Luke Fitzgerald, Tommy Bowe, Brian O’Driscoll, Keith Earls, Ronan O’Gara, Tomás O’Leary, Jamie Heaslip, David Wallace, Stephen Ferris, Alan Quinlan, Donncha O’Callaghan and Jerry Flannery are the other Irishmen travelling.
There had been widespread speculation 29-year-old O'Connell from Munster had been picked as captain ahead of Ireland's grand slam-winning captain Brian O'Driscoll and his selection was confirmed at a Heathrow hotel news conference at lunchtime.
O'Connell has 62 Ireland caps and three for the Lions, having played in all three tests of the 3-0 defeat in New Zealand in 2005.
He has helped Ireland to three triple crowns, occasionally stepping in as skipper, was the bedrock of the team that this year won their first Six Nations grand slam since 1948, and has won the Heineken Cup twice with Munster, captaining them to their 2008 success.
Coach Ian McGeechan takes a 37-man squad for the 10-match tour in South Africa, which includes Tests in Durban, Pretoria and Johannesburg.
The squad will depart on 24 May - a day after the Heineken Cup final.
In all there are 14 players from Ireland, 13 from Wales, eight from England and two from Scotland. Full squad to be listed shortly.
