AKIPRESS.COM - The royal wedding plans of Prince Harry and his American-bride-to-be Meghan Markle are firming up as the couple released more details Sunday of the nuptials while expressing thanks for the good wishes they've been showered with from around the globe,  ABC News reported.

The wedding will begin at noon on May 19 at St. George's Chapel at Windsor Castle, about 22 miles outside of London, Kensington Palace officials said in a statement Sunday.

The Right Rev. David Conner, the dean of Windsor, has been tapped to conduct the wedding service, while The Most Rev. Justin Welby, the Archbishop of Canterbury, will officiate when the couple takes their marriage vows, the statement reads.

Welby also performed the christening of Prince Harry's nephew, Prince George, in 2013.

Following the hour-long wedding ceremony, Harry and Markle plan to undertake a carriage procession that will start at St. George's Chapel, leave Windsor Castle via Castle Hill, continue along High Street through Windsor Town before returning to Windsor Castle on a route called the Long Walk.

After the carriage procession, the newlyweds will attend a reception at St. George's Hall, where they will rejoin their wedding guests. They will likely include Harry's grandparents, Queen Elizabeth II and Prince Philip; his father, Prince Charles; and his big brother, Prince William, and his wife, Kate Middleton, the Duchess of Cambridge.

While the official wedding guest list remains a closely guarded secret, the couple is expected to fill St. George's Chapel, which has a capacity to hold 800.
