Northern Ireland's deputy first minister Martin McGuinness smiles as he attends the British-Irish Council meeting at Stirling Castle in Scotland June 22, 2012. Former Irish Republican Army (IRA) commander McGuinness will meet Britain's Queen Elizabeth for the first time next week, marking a milestone in the province's peace process. The queen has never met a senior figure in the now-defunct IRA, which killed her relative Lord Mountbatten in 1979, or its political wing Sinn Fein. REUTERS/David Moir
