Britain's Supreme Court to rule on WikiLeaks chief

Britain's Supreme Court is due to rule Wednesday whether to approve the extradition of WikiLeaks chief Julian Assange to Sweden, a potential turning point in the Internet activist's controversial career.

Assange has spent the better part of two years fighting attempts to send him to Sweden, where he is accused of sex crimes stemming from a visit to the country in the summer of 2010.

The 40-year-old Australian, best known for revealing hundreds of thousands of secret U.S. documents, denies any wrongdoing.

If he loses, Assange could conceivably appeal to the European Court of Human Rights, which in the past has delayed high-profile extraditions for years on end.

But because Sweden is a fellow European country it's not clear whether an appeal would stop him from being sent there.
