Michelle Obama and the First Daughters on British Holiday

LONDON, June 9, 2009 — -- President Obama may have dominated European diplomacy in recent days, but Michelle Obama and their two young daughters have captured the headlines with their stealthy trip to London.

After causing a frenzy on Monday by having tea with the prime minister's wife at 10 Downing St., visiting Westminster, the Tower of London and a London pub, the first family slipped off the radar today.

There were widespread reports that the girls, Malia,10, and Sasha, 8, along with first lady Michelle Obama had been invited to visit the set where the final Harry Potter movie is being filmed, but the White House refused to confirm those reports.

Vanessa Davies, publicist for Harry Potter, denied there was a visit planned.

"There is no Obama visit, not as far as I know. I feel I would be in the loop if there was such a visit," said Davies.

On Monday, the Obamas startled and delighted the staff of The Audley pub in the Mayfair district across from the U.S. Embassy.

The Obamas made reservations for 25 people, although restaurant employees did not know in advance that the large party included the first family.

"We were all speechless when they walked in. I couldn't believe it," said Cintia Pinto, 24, one of the waitresses who served the Obamas.
