"It's wonderful news from St Mary's, Paddington, and I'm sure that right across the country and indeed right across the Commonwealth people will be celebrating and wishing the royal couple well. It is an important moment in the life of our nation, but I suppose, above all, it's a wonderful moment for a warm and loving couple who got a brand-new baby boy.”

The Canadian Prime Minister Stephen Harper said Canadians were delighted to learn of the arrival of the newest member of the royal family who would be a future sovereign of Canada.

Huge crowds have welcomed Pope Francis in the Brazilian city of Rio de Janeiro in his first overseas visit as head of the Roman Catholic Church. He joined a parade through the streets of Rio in an open vehicle, dismissing the authority’s advice to use a bullet-proof popemobile. The Argentine-born pope returns to his native South America to join more than a million Roman Catholics from all over the world in a youth festival. Here's Julia Carneiro.

Thousands of people have been crowding the streets of Rio city centre to greet Pope Francis outside the city's Metropolitan Cathedral. People in the city centre where the pope will pass on his popemobile are chanting, waving their arms and carrying flags of their countries. Over 300, 000 people registered for the World Youth Day, and here, there are flags from Mexico, Paraguay, and especially Argentina, where the pope was born and most foreign visitors are coming from.
