Putin has wished good health to the newborn, Duchess of Cambridge and all the members of the royal family.
The Duchess of Cambridge, Kate Middleton, gave birth to a baby boy on July 22 at 16.24 London time. The boy weighs 3.8 kilograms and will be the third in line for the British throne.
A bulletin with the news was put on the Buckingham Palace gate in line with tradition. It said that the Duchess and the boy were doing well and would remain in the hospital overnight.
A press release said that Duke of Cambridge and Queen Elizabeth's older grandson William was presented during the delivery.
A Buckingham Palace representative said that the Queen and the Duke of Edinburgh were delighted with the news.
Meanwhile, the British embassy in Russia has informed Facebook and Twitter users how they can send congratulations to Catherine, Duchess of Cambridge, and Prince William on the birth of their son.
The embassy has provided details of Facebook and Twitter pages where all Russian users can leave their greetings, an embassy spokesman told Interfax on Tuesday.
Cards can also be sent to the parents through the Google Plus server, he said, adding that instructions are provided.
Asked whether Muscovites came to the British embassy to convey their joy over the birth of the future king of Britain, he said he left the embassy early on Tuesday and did not see anyone. They must have been asleep that early, but some may come later in the day, he said.
