David Cameron today gushed over the 'incredibly romantic and moving' wedding service at Westminster Abbey.
He said the Royal Wedding represents 'the best of Britain', as he spoke of his pride at seeing William overcome the death of his mother to become a fine prince.
He arrived at Westminster Abbey with his wife Samantha, who broke with tradition by forgoing a hat or fascinator for a jewelled head piece.

She wore a 495 Burberry teal knee-length fitted dress with shoulder detailing and 75 nude shoes fromAldo. She also opted for a splash of colour with a burnt orange shawl and dramatic necklace.
The Prime Minister, who wore a morning suit after reversing his decision to wear a suit, also told how he had spent the night on the Mall before Charles and Diana's wedding in 1981.
But he said the celebrations were not simply about the 'handsome prince and the beautiful princess', adding: 'It's also about this incredible institution of the monarchy and the amazing public service that they have given over so many years and the extraordinary role that the Queen has played.
'I think people around the world will be watching this great historical moment and see the best of Britain and we do do these things very well.
'I slept on the Mall for Charles and Diana's wedding all those years ago and I suppose like many people my age have watched Prince William grow up and all the challenges he's had -obviously losing his mother, but now finding love and wanting to get married.

'So like anyone who's lived in Britain, you feel quite an attachment to this whole event and that's why I think the whole country's getting excited about it.'
Mr Cameron, still wearing his morning suit wedding attire, mingled with guests and tucked into cake before posing for pictures.
He said: 'The cupcakes were very good. Buckingham Palace was very good too.
'It has been an amazing day, the whole country has had something to celebrate.'
The Prime Minister described sitting in the abbey as 'like a fairytale'.
He added: 'It was beautiful to see two people who really love each other and who are incredibly happy at an amazing ceremony.
'It's a day when we see 'the new team'. It was incredibly romantic and moving.'
Mr Cameron said today was 'not just about the beautiful princess and handsome prince', but a day when Britain celebrated the monarchy itself.
'It's a great moment for Britain, a moment when everyone is celebrating and it's being watched round the world where people will see lots of things they love about Britain,' he said.
