From the BBC:

With Russia's presidential election campaign entering its last day, the head of the electoral commission has admitted media coverage was unequal.

Vladimir Churov told the BBC not all candidates had enjoyed equal access to the media, but he still believed the coverage had been fair.

Critics say TV channels have given too much time to Vladimir Putin's chosen successor, Dmitry Medvedev.

He is expected to win by a wide margin when Russians vote on Sunday.

Mr Putin himself is expected to address the nation on Friday to bid farewell to the public as president after eight years, Russian media say.

'Fair but not equal'

Mr Churov characterised coverage of the campaign as "fair but not equal".

"That's a problem not only for our country but I can agree that not all candidates have an equal number of news items," he said.
