Palestinian leader: Mahmoud Abbas
Former Palestinian Prime Minister Mahmoud Abbas, the candidate of the Fatah faction, won the January 2005 poll to replace the late Palestinian leader Yasser Arafat.
President Abbas succeeded Yasser Arafat as PLO leaderMr Abbas, also known as Abu Mazen, had already succeeded Yasser Arafat as leader of the Palestinian Liberation Organisation (PLO), having been Mr Arafat's deputy since 1969.
The surprise victory of the militant Islamic movement Hamas in parliamentary polls in January 2006 led to heightened tension between the Palestinian factions. There were recurring bouts of violence between Hamas and Mr Abbas's Fatah faction, raising fears of civil war. In February 2007, Hamas and Fatah agreed to form a government of national unity.
However, in June 2007 Hamas took control of the Gaza strip, seriously challenging the concept of a coalition, which Abbas subsequently dissolved.
Mr Abbas's current term was set to have ended in January 2009, but in 2008 announced he was extending his term by another year, in order to allow presidential and parliamentary elections to be held at the same time. The move was denounced by Hamas.
In November 2009, Mr Abbas said he would not stand again in elections scheduled for 24 January 2010, in protest against the continuing impasse in attempts to resurrect peace talks with Israel.
Many analysts regard Mahmoud Abbas as a moderate. He has condemned the armed Palestinian uprising and favours the resumption of negotiations with Israel. But he faces the challenge of persuading armed groups to stop their campaign of anti-Israeli attacks.
Mahmoud Abbas was born in 1935 in Safed, a town in present-day northern Israel. He co-founded Fatah - the main political grouping within the PLO - with Yasser Arafat in the late 1950s.
He established contacts with left-wing Israelis in the 1970s and was the main Palestinian architect of the 1993 Oslo accords, which led to the foundation of the Palestinian Authority.
His brief stint as premier was plagued by power struggles with Mr Arafat over the control of the Palestinian security apparatus and over planned reforms. Mr Abbas resigned in September 2003.
The former Palestinian leader Yasser Arafat died in a French hospital on 11 November 2004, aged 75.
