They arrived in Washington last night on a charted plane, and as the royal couple climbed the steps to Lincoln's memorial a well-wisher asked Charles how he was feeling. "Jet-lagged," the Prince of Wales responded.

At King's nearby memorial they were joined by leading figures from the US civil rights movement Jessie Jackson and Congressman John Lewis, who helped organise the famous Selma march.

During a visit to Washington's National Archive museum, the Prince was shown a telegram sent by the US Embassy in London on behalf of a young Charles to the State Department in 1957.

The document asked for instructions about the type of fuel that was required for a toy car that the heir to the throne had been given.

Charles also marked the 800th anniversary of Magna Carta by examining a 1297 copy of the historic document and also saw the US Declaration of Independence.

The royal couple also took a trip around Mount Vernon, where they lay a wreath at the tomb of George Washington before signing the guest book.

They even had time to meet Bubba the lamb on their travels.

Camilla also visited the Shakespeare Theatre Company where she toured the theatre, meeting its staff and young performers.
