Charles and Camilla will be crowned at London's Westminster Abbey on Saturday. The coronation follows a tradition dating back nearly a thousand years.

No US president has ever attended the coronation of one of Britain's kings. The White House said last month that Biden had told Charles he wanted to meet him later in the year. The event will take place against the backdrop of the financial crisis in the UK and the U.S., which has been hit by a series of high-profile bankruptcies.
