Participants agreed a $20 billion deal to stop extremist groups from getting hold of nuclear weapons, notably from stockpiles held in the former Soviet Union.

FRANCE - EVIAN - JUNE 2003:

-- The summit was marred by violent demonstrations.
UNITED STATES - SEA ISLAND, GEORGIA - JUNE 2004:

UNITED KINGDOM - GLENEAGLES - JULY 2005:

-- G8 leaders announced they would more than double aid to Africa by 2010, boosting spending by $25 billion a year from then.
-- They also said G8 nations and other donors would increase total aid for all developing countries by about $50 billion a year by 2010.

-- Group of Eight leaders launched a fresh bid to pin down an elusive global trade pact, seeking a positive outcome to a summit was riven by discord over the Middle East.
-- A formal agenda of energy security, combating infectious diseases and promoting education held little controversy and required no financial commitment by G8 members.
-- Russia had to concede to European Union concerns over its conduct in energy markets to get agreement on energy security. But it did not bow to demands to ratify the Energy Charter, an international rulebook for oil and gas market activity.
-- Assistance to Africa, put at the top of the 2005 summit by British Prime Minister Tony Blair but initially ignored by Russia for the 2006 meeting, also found its way on to the agenda.
