Burmese pro-democracy leader Aung San Suu Kyi has made a plea for the world's press to keep the spotlight on Burma in the BBC's first broadcast from its new London studios.
During the Burmese Service transmission from Broadcasting House, she said: "It's very important that the external media keeps up an awareness of what is happening in Burma because we don't really have absolute freedom of information. We don't have absolute freedom of the press.
"We must remember there is such a thing as censorship in the country."
The service, which has an estimated weekly audience of 8.3 million listeners in Burma, went on air in a move which will eventually see all the BBC's UK newsrooms brought under one roof.
BBC director general Mark Thompson said: "The Burmese Service is one of the jewels in the BBC's crown and I know is listened to and enjoyed by many millions of people in Burma.
"This is a great day for the BBC and the Burmese Service. The Burmese service is the very first service to make the move and to be broadcasting today from its new home."
