Washington: Joe Biden has formally won the Democratic Party nomination to face Donald Trump in November’s presidential election.
A candidate needs at least 1,991 delegates to secure the nomination. Biden crossed the threshold when results came late on Friday after seven states and the District of Columbia held presidential primaries earlier in the week.
The achievement was a formality after Biden became the presumptive nominee when his main rival, Vermont Senator Bernie Sanders, quit the race in April.
He had been the effective nominee since Bernie Sanders withdrew in April.
Biden, who served as Barack Obama’s vice-president, began the primary campaign in faltering style in Iowa and New Hampshire, but then built momentum with a convincing victory in South Carolina.
He then dominated the so-called Super Tuesday contests, taking 10 of the 14 states.
Biden, 77, secured the nomination officially after seven states and the District of Columbia held presidential primaries on Tuesday.
It is his third bid for the presidency.
Associated Press puts his tally at 1,995 delegates, with eight states and three US territories still to vote.
