Bernie Sanders has won the New Hampshire Democratic primary contest, on a terrible night for former vice-president Joe Biden, reports BBC.

The left-wing senator took a tight victory over centrist former mayor Pete Buttigieg, who offered a different Democratic vision in the race to take on US President Donald Trump in November.

Mr Sanders declared the night “the beginning of the end” of Mr Trump.

The race moves next to the Nevada caucuses on 22 February.

What happened in New Hampshire?

Some 280,000 Democratic voters cast ballots in the Granite State on Tuesday night, delivering 26% to Mr Sanders.

With 95% of the vote counted, Mr Sanders, 78, led Mr Buttigieg, the 38-year-old the former mayor of South Bend, Indiana, by only 1.6%, or about 4,300 votes.

What’s next in the race?

The candidates will look to post strong performances in Nevada and South Carolina, to show that they can appeal to a more diverse electorate.

Then, on Super Tuesday, 3 March, 15 states and territories – with 1,344 delegates – will vote.

The field will be whittled down until a final nominee is crowned at the party convention in Milwaukee, Wisconsin, in July.
