James Martin Pacelli McGuinness (Irish: Máirtín Mag Aonghusa; born 23 May, 1950) is an Irish Sinn Féin politician and the current deputy First Minister of Northern Ireland. He was born in Derry, Northern Ireland.
A former Provisional Irish Republican Army (IRA) leader, McGuinness is the MP for the Mid Ulster constituency. Like all Sinn Féin MPs, McGuinness practises abstentionism in relation to the Westminster parliament. He is also a member of the Northern Ireland Assembly for the same constituency.
Following the St Andrews Agreement and the Assembly election in 2007, he became deputy First Minister of Northern Ireland with the Democratic Unionist Party (DUP) leader Ian Paisley becoming First Minister on 8 May 2007. On 5 June 2008 he was re-appointed as deputy First Minister to serve alongside Peter Robinson, who succeeded Paisley as First Minister on that date. McGuinness previously served as Minister of Education in the Northern Ireland Executive between 1999 and 2002.
