Harry's trip to London 'in-and-out,' sources say
Sources told ABC News royal contributor Omid Scobie that Prince Harry, Duke of Sussex, will be heading back to the United States soon after attending his father's coronation in London on Saturday.
"I'm here on the Duke of York steps, we've just seen the procession go back to Buckingham Palace and for Prince Harry, the Duke of Sussex, that probably brings his very quick trip to London to an end," Scobie said. "We saw him arrive on Friday evening getting ready, of course, for the big day to support his father at the coronation ceremony."
"But, of course, he also has duties back in Montecito, California, and sources close to the duke say that it is going to be an in-and-out trip for him," he added. "Just here to be part of that moment in Westminster Abbey, support his father and then be back at home to support his own family in Montecito."
