Demonstrators across Russia have called for a rerun of last weekend's parliamentary elections, which were officially won by the party of the Prime Minister Vladimir Putin. The biggest protest was in Moscow, where about 50,000 people gathered on a square. Many waved flags and carried white carnations. From Moscow, Steve Rosenberg reports.

Not since the fall of the Soviet Union have so many Russians taken to the streets to take on their leader. In the middle ages, Bolotnaya Square was a place for executing criminals. Today tens of thousands of Muscovites came here to accuse the authorities of committing a crime: stealing their votes. They demanded a rerun of the parliamentary election and the resignation of Vladimir Putin. It was a diverse crowd: there were communists, ultra-nationalists and Western-leaning Russian liberals. But for today at least, they were united in their condemnation of government.

The South Africa[n] government, which is hosting a United Nations climate change conference, says agreement has been reached on many key issues. However, the South African draft text does not specify a legally binding deal. From Durban, here's Richard Black.

Ministers spent about four hours locked in a small crowded room, aiming to find common ground. According to the South African host government, they did it. But others are not so sure. The EU and many countries that are vulnerable to climate change have been fighting for a road map leading to a new legally binding global agreement as soon as possible. Sources indicate that the South African draft text does not specify a legally binding deal and envisages the agreement coming into force only after 2020. That's far too late for small island nations in the Pacific and Caribbean who fear inundation by rising seas.
