Kremlin accused of opposition phone call leaks

One of Russia's leading opposition figures, Boris Nemtsov has had hours of his private phone conversations leaked to a pro-government news website.

In them he is heard insulting some of his own supporters as 'internet hamsters' and 'scared penguins.'

Mr Nemtsov, a deputy prime minister in the 1990's, says the leak was intended to provoke division within the opposition movement, but has only brought them closer together.
