Prince William and Kate Middleton anniversary expected to be quiet affair

Sunday, April 29 will mark the one-year anniversary of Prince William's marriage to Kate Middleton, now officially known as Catherine, Duchess of Cambridge. The wedding was certainly not a private affair - it was attended by many and viewed by millions all over the world - but their first-year anniversary celebration is going to be just the opposite.

William is home from the Royal Air Force and palace officials have said that he and Kate plan to celebrate their anniversary on Sunday in private. On Thursday, William and Kate visited the London headquarters of the MI6 intelligence agency and attended a reception together (pictured above).
