William Meets Obama In The Oval Office While Kate Tours Centre For Child Development In Harlem

The British monarchy, historically not the most welcome institution in Washington, was well received at the White House on Monday as Prince William met with President Obama in the Oval office, part of the Duke and Duchess of Cambridge’s three day tour of the US.

More than 250 miles north, the Duchess carried out her own solo engagement, meeting with New York’s First Lady, Chirlane McCray, before visiting the Northside Centre for Child Development in Harlem. The pregnant Duchess, whose hair was half swept back and who was wearing a black coat by Goat with white edging, was greeted with cheers from spectators across the street. The centre provides educational and mental health services to about 3,300 children and families each year.

It is the couple's first visit to the US since 2011 and their first to New York or Washington. William is delivering a major speech on the illegal wildlife trade in Washington after meeting Obama and vice president Joe Biden.
