Queen Elizabeth II has invited the President of the United States to make a State Visit to the United Kingdom. This will be the second State Visit to the United Kingdom by an American President. The first State Visit was in 2003 by President George Bush.
In 1918, President Woodrow Wilson stayed at Buckingham Palace, but the American president was not on a State Visit. In 1982, President and Mrs. Reagan were guests of the Queen at Windsor, but this visit was not considered a State Visit.
The invitation from the Queen was presented to President Obama by British Prime Minister David Cameron yesterday.
The state visit is expected to take place in 2011.
