The royal love affair that caused a king to abdicate
There are now 98 days to go until the most anticipated wedding in decades...that of Prince William and Kate Middleton.

She was deemed unacceptable, so the king chose to give up his throne for love.
The abdication triggered a crisis which shook the British monarchy to the core.
Katty Kay looks back at the event.
