Claim: Tony Blair was involved in the Northern Ireland peace process of the 1990s.

Anthony Charles Lynton Blair -LRB- born 6 May 1953 -RRB- is a British politician who served as Prime Minister of the United Kingdom from 1997 to 2007 and Leader of the Labour Party from 1994 to 2007 . He remains the most recent Labour Party leader to have won a general election .   From 1983 to 2007 , Blair was the Member of Parliament -LRB- MP -RRB- for Sedgefield . He was elected Labour Party leader in July 1994 , following the sudden death of his predecessor , John Smith , who together with his predecessor , Neil Kinnock , had started to move the party closer to the political centre , in the hope of winning power . Under Blair 's leadership , the party used the phrase `` New Labour '' , to distance it from previous Labour policies and the traditional conception of socialism . Blair declared support for a new conception that he referred to as `` social-ism '' , involving politics that recognised individuals as socially interdependent , and advocated social justice , cohesion , the equal worth of each citizen , and equal opportunity , also referred to as the Third Way . Critics of Blair denounced him for having the Labour Party abandon genuine socialism and accepting capitalism . Supporters , including the party 's public opinion pollster Philip Gould , stated that after four consecutive general election defeats , from 1979 to 1992 , the Labour Party had to demonstrate that it had made a decisive break from its left-wing past , in order to win an election again .   In May 1997 , the Labour Party won a landslide general election victory , the largest in its history , allowing Blair , at 43 years old , to become the youngest Prime Minister since 1812 . In September 1997 , Blair attained early personal popularity , receiving a 93 % public approval rating , after his public response to the death of Princess Diana . The Labour Party went on to win two more elections under his leadership : in 2001 , in which it won another landslide victory , and in 2005 , with a reduced majority . In the first years of the New Labour government , Blair 's government introduced the National Minimum Wage Act , Human Rights Act , and Freedom of Information Act . Blair 's government also devolved power , establishing the Scottish Parliament , the National Assembly for Wales , and the Northern Ireland Assembly . In Northern Ireland , Blair was involved in the 1998 Good Friday Agreement .   Blair strongly supported the foreign policy of the Bush administration , and ensured that the British Armed Forces participated in the 2001 invasion of Afghanistan and , more controversially , the 2003 invasion of Iraq . Blair has faced strong criticism for his role in the invasion of Iraq , including calls for having him tried for war crimes and waging a war of aggression . In 2016 , the Iraq Inquiry strongly criticised his actions and described the invasion of Iraq as unjustified and unnecessary . Blair also intervened militarily in Kosovo and Sierra Leone .   Blair was succeeded as the leader of the Labour Party and as Prime Minister by Gordon Brown in June 2007 . On the day that Blair resigned as Prime Minister , he was appointed the official Special Envoy of the Quartet on the Middle East , an office which he held until May 2015 . He now runs a consultancy business and has set up various foundations in his own name , including the Tony Blair Faith Foundation .
