Russian election protests a political reawakening'

Thousands of people have attended the biggest anti-government rally in the Russian capital Moscow since the fall of the Soviet Union.

As many as 50,000 people gathered on an island near the Kremlin to condemn alleged ballot-rigging in parliamentary elections and demand a re-run.

Other, smaller rallies took place in St Petersburg and other cities.

The BBC's Daniel Sandford was in Moscow and said the protests were a "political reawakening for people in Russia and a political awakening for a new generation".
