Charles said in a statement that "it is a great joy to have another grandchild, the only trouble is I don't know how I am going to keep up with them."

As the new family of five spent time at home at Kensington Palace, the birth was marked Tuesday by bell ringing at Westminster Abbey and gun salutes in Hyde Park and at the Tower of London.

The new baby is a sixth great-grandchild for Queen Elizabeth II and is fifth in line to the throne after Charles, father Prince William and his two older siblings.

William and Kate have not yet disclosed the name of the infant prince. Bookmakers say Arthur is the favorite in betting, followed by James and Albert.

The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news.
