How will police keep safe the nearly one million spectators who will be lining the London streets on Friday for the Royal Wedding?

Roy Ramm, former commander of specialist operations at New Scotland Yard, shares how security is preparing for the big day, how the weather will affect screenings, and how they will react if a disruption occurs.

The planning, Ramm tells AM's Kiran Chetry, has been going on for months. He explains the precautions taken and who police have already pre-screened as potential disruptors.

Prefer your Royal Wedding with a spot of tea?

AM’s Kiran Chetry kicks off her London at the Dorchester with CNN International’s Zain Verjee. She explores the British tradition over high tea and sandwiches.

American interest in Britain’s upcoming royal wedding is a reflection of the historic bonds the two countries share. Winston Churchill first coined the bond a “special relationship.” The phrase has been renewed throughout the years, but like any relationship it has had it’s ups and down.

AM’s Kiran Chetry traces the two countries’ friendship and diplomacy. When did it begin and at what moments did it fade? Kiran talks to historian David Woolner of the Roosevelt Institute  and former British Prime Minster Gordon about the “unbreakable” relationship.
