Harris unchallenged as Democrats vote for White House nominee

She has support of 99% of delegates who signed petitions ahead of electronic ballot

Ms Kamala Harris will be confirmed as the Democratic US presidential nominee in an electronic vote, which started on Aug 1 and replaced the fanfare of in-person balloting that usually kicks off the party's national convention.

Less than two weeks after Mr Joe Biden ended his re-election bid, his 59-year-old vice-president is in full control of the party, having emerged as the only Democrat in the running to challenge Republican Donald Trump in November.

Just under 4,000 delegates, the grassroots activists and politicians allocated during the primary process, sent in signatures backing Ms Harris to be on the ballot for the five-day electronic vote.

No other Democrats have stepped forward to challenge her elevation to the top of the ticket, making her confirmation as the first black and South Asian woman ever to secure a major party's nomination a formality.

She won the support of 99 per cent of the delegates who signed petitions, the Democratic National Committee (DNC) said in a statement, while no one else met the qualifying threshold of 300 signatures.
