London, Dec 21 : British Prime Minister Gordon Brown Monday accused a "handful of countries" of preventing a climate change treaty at last week's Copenhagen conference and vowed that there would be no repeat of the "chaotic proceedings".

Speaking via video link to a meeting in London, Brown said he was still determined to achieve a binding international treaty on climate change targets and would urge an immediate reform in the UN negotiating process for such large gatherings.

The Copenhagen negotiating process had been "chaotic" with "last-minute negotiations being dominated by threats and fear," said Brown, without spelling out whom he had in mind.

"We should not allow a handful of countries to hold us back," said Brown, who welcomed the follow-up conference proposed by German Chancellor Angela Merkel.

He added that he remained optimistic about the future of tackling the consequences of climate change, as "one country after the other declares itself a pioneer in the fight against climate change."(DPA)
