US President Joe Biden has won New Hampshire’s largely symbolic Democratic primary, prevailing in an unusual write-in effort after he refused to campaign or appear on the state ballot.

Mr Biden easily defeated his main challengers, Minnesota representative Dean Phillips and self-help author Marianne Williamson, two outside contenders who were on the ballot along with a host of little-known names.
