President Obama and his lovely wife Michelle have arrived in the UK for their three day state visit.  They visited Ireland first as he had ancestors there and wanted to trace his roots but they left earlier than planned as the UK is expecting ash cloud from Iceland anytime now.

The President and his wife were greeted by Prince Charles and the Duchess of Cornwall and then went off to Buckingham Palace to meet Prince William and the new Duchess of Cambridge along with the Queen and Prince Philip.
