Royal watchers the globe over are a buzz with excitement at the prospect of one of the biggest royal weddings of the last few decades.
But the burning question is when and where will Kate Middleton and Prince William tie the knot?
The official announcement said the couple would wed in London.
And the most likely venues have been named as Westminster Abbey and St Paul's Cathedral, where William's father wed his mother Princess Diana in 1981.
As far as dates go, sources have hinted that July 8 is one of the strongest possibilities.
August 12 and 13 are also being touted as possibilities, after aides have apparently made discreet overtures' to senior Westminster Abbey staff about those dates.
