Londoners will be able to watch the royal wedding on April 29 on giant screens at the capital’s royal parks and also in Trafalgar Square.

The public can also watch the event live from the arrivals at Westminster Abbey, the procession from the Abbey to Buckingham Palace and the wave from the Palace balcony.

London Mayor Boris Johnson said: ‘The Royal Wedding is a fantastic opportunity for Londoners and visitors to come together for a magnificent celebration, in Trafalgar Square, in Hyde Park, or at one of the many street parties taking place across the capital. Amidst the pageantry and tradition, the whole world will experience why London is the greatest city to live, work and visit.’

Rain is predicted for the day of the royal wedding, which could mean that Prince William and Kate Middleton ride in a glass carriage rather than an open top carriage.

The Royal Carriage Procession carrying the couple will be escorted by police officers on horseback, including nine grey horses.

Security will be tight during the event following threats from Al Qaeda, Irish dissident groups and anarchists.
