PRESIDENT George Bush today delivered a farewell address, paying tribute to his successor as a man whose story reflects "the enduring promise" of America.

The outgoing head of state said the inauguration of Barack Obama - the US's first black president - would be "a moment of hope and pride" for the nation.

Turning to his own tenure, he acknowledged there had been setbacks, stating: "There have been good days and tough."

But in a 15-minute speech, he added that the role had been "a privilege of a lifetime".

The address quickly turned to the decisive moment in Mr Bush's eight years as president - the September 11 terrorist attacks.

President Bush said as a result of America's actions, Afghanistan had been turned from Taliban control into "a young democracy".

Meanwhile, Iraq has gone from "a brutal dictatorship" to a "friend of the United States".
