World leaders are heading into the second day of the G8 summit, with rising food and fuel costs still on the agenda and deep divisions over climate change.

They are trying to thrash out the wording of a statement that would allow US President George W Bush to sign up to a global goal of reducing greenhouse gas emmissions.

There have been accusations some rich nations are reneging on promises to increase aid to Africa.

European Commission President Manuel Barroso said: “What I would like leaders to do is instead of saying ‘I will do nothing unless you do it first’ we change the logic of it, we say, ‘let’s go for it together’.”

Before the eight-course dinner, the Russian President and his US counterpart met face to face, with Bush describing Medvedev as a “smart guy”.

Medvedev also met British Prime Minister Gordon Brown. However there was no progress on divisive issues including Moscow’s refusal to extradite the suspected murderer of the dissident former spy, Alexander Litvinenko.

Anti-G8 protesters were stopped by police when they tried to approach the venue. Security is ultra-tight, with 21,000 officers drafted in for the summit.
