The biggest security operation in a generation was hailed as a "huge success" today as police delivered on their promise to deal robustly with potential wedding troublemakers.
As the royal couple arrived at Buckingham Palace, police revealed they had made 43 arrests among the crowd to ensure the event went smoothly.
Officers swooped on two minor anti-wedding protests in central London but said scenes were calm.
A police source said: "It's all gone to plan so far, it's fantastic."
The arrests were made "within and outside the event footprint", Scotland Yard said.
Offences included an allegation of a sex attack on a 14-year-old girl, criminal damage and 25 breaches of the peace.
Ninety nine people were banned from the City of Westminster as more than 5,000 officers ensured the event went like clockwork.
