Zara Phillips and Mike Tindall prepare for wedding in Edinburgh

Three months ago, Zara Phillips was a guest as the world watched Kate Middleton marry her prince in a lavish and very public ceremony.

Now it's the turn of Queen's eldest granddaughter to step into the spotlight, as she ties the knot with rugby star Mike Tindall on Saturday.

Like the duke and duchess's wedding, the Queen and Duke of Edinburgh will be in attendance, but this weekend's nuptials in Edinburgh - already dubbed "the other" royal wedding - is set to be a world away from April's ceremony.
