Royal wedding: Syria ambassador off wedding list
Many of the 2,000 guests at the royal wedding will be there because official protocol demands it, and this has caused some controversy.
Syria's ambassador has been told he is no longer welcome following his government's violent crackdown on pro-democracy demonstrators.
The decision not to invite two former Labour Prime Ministers - Gordon Brown and Tony Blair - has also caused debate.
