Rich and poor nations must work together and leave the Copenhagen climate summit with heads held high the Brazilian President Luiz Inacio Lula da Silva has told delegates.

Expressing frustration over an apparent failure to reach a deal he said Brazil was ready to make sacrifices and help – financially – countries most vulnerable to climate change.

“I’d love to get out of here having signed the most perfect document in the world. If we haven’t drafted such a document so far, I don’t know if an angel, or a wiseman will descend in the plenary session and place in our heads the intelligence we have been lacking up until now”.
