Central London faces a three-day traffic shutdown for the royal wedding as key roads are closed off.

Authorities securing Prince William and Kate Middleton's procession route between Buckingham Palace and Westminster Abbey  say it could be blocked off for three days or more.

 

There will be the added difficulty of preparing for the one million well-wishers expected in London that day.

Motorists are likely to be asked to steer clear of central London.

 

The route taken by Miss Middleton on her way to the abbey will be closed in advance for police security checks. It could see her leaving Buckingham Palace, St James's Palace or Clarence House and travelling with her father Michael in a large-windowed limousine via The Mall, Horse Guards Parade, Whitehall and Parliament Square.

 

But the shutdown could be far wider, possibly closing key junctions such as Hyde Park Corner, Trafalgar Square and the area around Victoria station on the wedding day.
