The countdown is over: this morning, after months of anticipation, Britain’s Prince William is marrying Kate Middleton. The wedding is in progress right now. And all this morning, we'll be bringing you live updates from both sides of the pond. We go first to Buckingham Palace where we're joined by the BBC's Laura Lynch and Paddy O'Connell. And for reaction from U.S.-based Brits we'll hear from The Takeaway's Kristen Meinzer, live from Greenwich Village, New York.
