Indonesia's president-elect has finally given his victory speech, almost three weeks after the country's first direct presidential poll.
Yudhoyono promised to be a leader to all Indonesians
Susilo Bambang Yudhoyono won by a huge margin, giving him a powerful mandate, which he has promised to use well.
The incumbent, Megawati Sukarnoputri, indirectly acknowledged defeat by declining to file a challenge to the result by the official deadline.
"This is a new era in our history," Mr Yudhoyono said.
"It holds great promises but there are also serious challenges ahead," he said, and few would disagree with that.
A statesmanlike speech
Dressed in a traditional loose batik shirt, Mr Yudhoyono spoke in Indonesian and English, ensuring that his message would be heard at home and abroad.
He thanked outgoing President Megawati for her role in ensuring a smooth election and called on her supporters to accept the result.
"There's a time to compete and a time to unite. I promise to be a president for all Indonesians, and I'll carry this precious mandate I've been given with the greatest sense of responsibility," he said.
Mr Yudhoyono said his initial priorities were to finalise his cabinet, set a programme for his government's first 100 days in office and ensure a smooth transfer of power.
He promised to take immediate steps to stimulate Indonesia's sluggish economy, and to lead a new drive against corruption.
But in keeping with his election campaign, he declined to give details.
This was, however, a statesmanlike speech, clearly designed to set a fresh tone on Indonesian politics.
Mr Yudhoyono, unlike his reticent predecessor, recognises the need to communicate his policies to the public and he is clearly aware of the huge expectations which face him.
