In September, Crown Prince Willem-Alexander and his wife, Princess Maxima, will visit New York to participate in NY400 activities. The Prime Minister will ask if you can receive their Royal Highnesses at the White House. The DUTCH stress the Crown Prince will likely be king soon (it is widely anticipated QUEEN Beatrix will abdicate within a year) and this would be an opportunity for the President to meet the Crown Prince in the context of the NY400 festivities. The Crown Prince is a champion around the world for clean water and sanitation as a public health initiative.
