In the US, Barack Obama has accepted the Democratic nomination for the presidency, making him the first black candidate to run for office. He was speaking in a packed stadium in the centre of Denver, from where our correspondent Kevin Connolly reports:

OBAMA:
I accept your nomination for presidency of the United States.

The night on which a major American party acclaimed a black presidential candidate for the first time called for something unique by way of theatre and Barack Obama obliged. In the rock star setting of a cavernous football stadium, on a stage decorated with columns that looked suspiciously like those of the White House itself, he delivered a speech that touched on everything - from motherhood to mortgage debt.

It was strong on patriotism and the readiness to use force as a last resort, but longer on talk of rebuilding areas of American life, which he said, had been fractured in the era of George W Bush:

OBAMA:
In Washington they call this the Ownership Society. But what it really means is that you are on your own. Out of work? Tough luck, you are on your own. Born into poverty? Pull yourself up by your own boot straps. Even if you don't have boots you are on your own.

Topped off with red, white and blue fireworks and confetti fired from stage side cannons, it produced rapturous applause inside the stadium. Its real political test though is how it will play in the uncommitted America that lies beyond.
