Prime Minister Gordon Brown said yesterday that a second summit of oil producers and consumers would be held in December in London.

Mr Brown said the London meeting was part of a process following on from a similar meeting in Jeddah and taking forward recommendations on energy security and climate change made at the Group of Eight rich nations summit in Japan.

"We've decided on an energy forum that will be convened by the Japanese themselves over the next few weeks. It will meet by September, in the autumn," Mr Brown told reporters. "It will then feed its recommendations into the consumers/producers dialogue that we're having with oil and energy producers and consumers, that we're having in London in December," he said.

In its statement on the world economy, G8 leaders said they were looking forward to the London summit, saying more enhanced dialogue and partnership were needed to promote global energy security.
