LONDON (AP) — President Barack Obama has arrived in London for a three-day visit that will include dining with the royal family and talks with Prime Minister David Cameron.

The president is visiting Britain after talks in Saudi Arabia with Persian Gulf allies.

The president will be joined in London by Michelle Obama and they will have lunch Friday with Queen Elizabeth II — a day after her 90th birthday. They'll also attend a dinner hosted by Prince William, his wife, Kate, and Prince Harry at Kensington Palace.

Obama is expected to speak out in opposition of Britain's exit from the European Union as he meets with Cameron on Friday. The president's intervention in the so-called "Brexit" debate has already sparked criticism from some who say he's meddling in Britain's business.
