British Prime Minister David Cameron on Monday reacted to the birth the royal baby boy, the first child of Catherine, Duchess of Cambridge, and husband Prince William.
"It is an important moment in the life of our nation," said Cameron. "But I suppose above all, it's a wonderful moment for a warm and loving couple who got a brand new baby boy."
Cameron referenced recent royal events that garnered excitement not only in Britain, but also internationally, namely the royal wedding of William and Catherine in April 2011, and Queen Elizabeth II's Diamond Jubilee last June, which celebrated her 60-year reign.
"It's been a remarkable few years for our royal family, a royal wedding that captured people's hearts, that extraordinary, magnificent jubilee, and now this royal birth, all from a family that have given this nation so much incredible service," said Cameron.
The Duke and Duchess of Cambridge spent some time with their new son before calling family members – starting with Queen Elizabeth II – to announce the birth, a Kensington Palace source told CNN royal correspondent Max Foster.
"They can know that a proud nation is celebrating with a very proud and happy couple tonight," said Cameron.
The British monarch is also head of state in 15 Commonwealth countries, including Australia, Canada, New Zealand, Belize and Jamaica.
"Right across the country, and indeed right across the commonwealth, people will be celebrating and wishing the royal couple well," said Cameron.
The baby will be third in line for the throne now occupied by the queen. Her son, Charles, will succeed her, followed by his son, William.
