Stephen Fry has urged the Prime Minister to support a campaign to strip Russia of the 2014 Winter Olympics amid concerns about anti-gay laws passed in the country.

Politicians in Russia's lower house of parliament, the Duma, have passed a law imposing heavy fines for providing information about homosexuality to people under 18.
Last month the IOC said it had "received assurances from the highest level of government in Russia that the legislation will not affect those attending or taking part in the Games."
