May the president’s wife touch the queen?

It’s such a relief to have this issue settled!  Thank you, thank you, Buckingham Palace:

First lady Michelle Obama did not breach protocol by touching Queen Elizabeth II at a reception for world leaders attending the G-20 summit, Buckingham Palace told CNN Thursday.

“It was a mutual and spontaneous display of affection and appreciation between the Queen and Michelle Obama,” the Royal Press Office said in a statement Thursday. “The London Summit reception at Buckingham Palace was an informal occasion,” the statement also said.

No breach of protocol occurred, according to the Royal Press Office, because Buckingham Palace does not issue instructions about how to address the Queen.
