Britain will celebrate the marriage of another member of the royal family on Saturday.

Queen Elizabeth's eldest granddaughter, equestrian star Zara Phillips, will marry rugby player Mike Tindall in Scotland. Their nuptials follows the late April media-frenzied wedding of Prince William to Kate Middleton.

Both will attend Saturday's wedding, which by royal standards is being described as a modest affair. Queen Elizabeth will lead the royal contingent to the ceremony in Edinburgh.
