William, Kate and Harry to host Barack and Michelle Obama for dinner on Friday
The Duke and Duchess of Cambridge and Prince Harry are to host US president Barack Obama and his wife Michelle for dinner on Friday, Kensington Palace has announced.
Mr Obama and the First Lady will dine at Kensington Palace after joining the Queen for lunch at Windsor Castle - the day after her 90th birthday celebrations.
"Their Royal Highnesses are very much looking forward to welcoming President and Mrs Obama to Kensington Palace," a statement from Kensington Palace said.
Mr Obama and his family have forged a warm relationship with the royals during the president's time in office.
They met William and Kate in May 2011 when the Cambridges carried out their first royal duty as a married couple - less than a month after their wedding. Newly-weds William and Kate greeted the Obamas in the 1844 room of Buckingham Palace at the start of the US state visit to the UK.
William also met Mr Obama in the Oval Office in Washington DC in 2014 when the Duke told him he was so excited after the birth of Prince George that he forgot to ask whether he was a boy or a girl.
Last year, Mrs Obama took time out of her whirlwind trip to Britain to present gifts to Prince George and his newborn sister Princess Charlotte.
Mrs Obama met the young royals at a private reception at Kensington Palace, where she presented the two young children with presents.
She gave baby Charlotte an American-made Amish rocking chair and a personalised Alpaca baby blanket and George a red American-made children's wagon known as a Berlin Flyer P-Wee Wagon.
Prince Harry has a close friendship with Mrs Obama in particular - through his support of wounded military personnel and work with the Invictus Games, a Paralympic-style championship for injured military personnel from across the globe. Mrs Obama is a keen supporter of forces' families in the US.
The Obamas will also come bearing a birthday gift for the Queen and join her for lunch on Friday - the day after her 90th - in the private dining room of her much-loved Berkshire residence Windsor Castle.
When the Queen hosted the Obamas at Buckingham Palace in 2011, the First Lady was seen putting her arm around the monarch's waist, showing how the women had become firm friends.
In an ITV documentary to mark the Queen's 90th birthday, Mr Obama praised the Queen for her "generous human touch" as he credited the monarch with helping to ensure the lasting special relationship between the UK and America.
