Georgia would provide enough electoral college votes to take the Democrat above the crucial threshold of 270, if he can hold onto his lead in Arizona. Arizona was declared for Mr Biden early on by several networks, but is now being watched closely.

Election officials say more than 99 per cent of the vote has now been counted in Georgia, with both candidates on about 49.4 per cent of the nearly 5 million votes cast in the state.

Mr Trump won Georgia by a sizeable 5 points in 2016, taking 51 per cent to Hillary Clinton’s 46 per cent.

Georgia has been reliably Republican since 1972, except when a southern Democrat was on the ticket – Georgians sided with native son Jimmy Carter in 1976 and 1980 and Bill Clinton in 1992.
