Only about 1500-2000 people will be able to squeeze into the tiny area in front of the Canongate Kirk on Saturday when "two sports personalities" marry. The bride is Miss Zara Anne Elizabeth Phillips, former world champion equestrian, and she will marry English rugby star Michael James Tindall.
This is a private wedding. No details, including the the Order of Service, will not be released to the public. The wedding will not be televised, nor will there be coverage in Hello!, apart from photos taken outside.
The couple will hold a "brief drinks reception" on board the former royal yacht, Britannia, which is docked at the Firth of Forth. Queen Elizabeth II and the Duke of Edinburgh, who are the bride's maternal grandparents, will not be attending this reception. They will come down from Balmoral early on Saturday.
The bride will be spending Friday night at Holyrood Palace. She and her father, Mark Phillips, will be driven the 400 yards from the palace to the church. Senior members of the British royal family, including the Prince of Wales and the Duchess of Cornwall, the Duke and Duchess of Cambridge, and Prince Harry, are expected to attend.
