Harry Potter premiere to take over Trafalgar Square

The world premiere of the final Harry Potter film, Harry Potter And The Deathly Hallows Part 2, is to take over London's Trafalgar Square.

The world famous landmark has been chosen in part because of building work in Leicester Square, where most UK premieres are traditionally held.

Organisers say they have had to change plans as parts of the usual site are boarded-up.

Daniel Radcliffe, Rupert Grint and Emma Watson will all be at the July launch.

The stars will walk the red carpet and be interviewed in Trafalgar Square, before heading the short distance to Leicester Square to see the film.

Unusually, more than one Leicester Square cinema will be used for the premiere screening on July 7.

When the first part of Harry Potter And The Deathly Hallows premiered back in November 2010, some fans queued for almost two days to have a front row view of the stars.
