The Latest: Obama arrives for lunch with Queen Elizabeth II

LONDON (AP) — The Latest on President Barack Obama's visit to the United Kingdom (all times local):

1:00 p.m.

President Barack Obama has arrived in Windsor, England, for a royal lunch with Queen Elizabeth II.

The two heads of state were sitting down at Windsor Castle, just west of London, on Friday. It's the day after the queen and much of Britain celebrated her 90th birthday. First lady Michelle Obama and Prince Philip, the queen's husband, were joining the meal.

Obama says he'll wish the queen a happy birthday in person.

The queen and Prince Philip came out to greet Obama and the first lady in a light drizzling rain as they disembarked from Marine One at Windsor Castle.

Obama's socializing with the British royals was continuing later Friday over dinner with Prince William, his wife Kate and brother Prince Harry at Kensington Palace in London.

He was meeting with Prime Minister David Cameron in between the royal engagements.
