Copenhagen, Dec 19 - Prime Minister Manmohan Singh extended his stay here another night Friday as consensus on a Copenhagen accord continued to elude representatives of 192 countries gathered here for the climate summit.

An Indian official told IANS that the prime minister had taken part in the talks between heads of state over dinner in an effort to stitch together a Copenhagen accord that would indicate the resolve of world leaders to fight climate change.

Manmohan Singh had returned to his hotel after that, the official said, while negotiators continued to labour over every word of the accord late into the night. (IANS)
