John McCain: 'US global leadership adrift'

Arizona Senator John McCain has told the Republican convention that US global leadership has drifted in the four years of the Obama administration.

Speaking in Tampa, Florida, Mr McCain added: "We can't afford to give governments in Russia and China a veto over how we defend our interests and the progress of our values in the world."

On Tuesday, after a delayed start to the gala on account of Hurricane Isaac, Republicans officially nominated Mitt Romney to represent their party in the race for the White House.
