World leaders have gathered in Prague for the funeral of Vaclav Havel, who led Czechoslovakia's revolution in 1989 and became president.

Dominik Duka, the Archbishop of Prague, was to lead the funeral Mass in St Vitus Cathedral, the biggest church in the country.

The dignitaries attending the funeral included David Cameron, US Secretary of State Hillary Clinton and her husband, former president Bill Clinton, Nicolas Sarkozy, German President Christian Wulff and Czech-born former US Secretary of State Madeleine Albright.

The funeral proceedings were broadcast on giant screens at Prague Castle and Hradcany Square.

Havel, the world-renowned playwright and the leader of the "Velvet Revolution," died on December 18 at the age of 75.
