Royal wedding: Who will walk Markle down the aisle?

Uncertainty remains over who will walk the royal bride, Meghan Markle down the aisle come Saturday. Her father Thomas Markle, who has never met his daughter's fiance, has swayed between confirming his attendance and then reneging on that promise. The latest report is that he has had a change of heart and wants to attend, but reported claims of chest pains for the seventy-two-year-old may prevent him from flying. But there are also reports he has been embarrassed by reports he staged paparazzi photographs. Dickie Arbiter is a former Press officer at Buckingham palace and joins Susie Ferguson with the latest details.
