Hillary Clinton wins final Democratic primary in the US capital

Hillary Clinton has won the last Democratic primary election, held in the US capital, officially wrapping up a long and brutal slog to secure votes for the party’s nomination.

The win over Bernie Sanders was mostly symbolic, as the former top diplomat last week secured the number of delegates needed to become the Democratic nominee for president when the party holds its convention in Philadelphia next month.

Clinton won 78.7 per cent of the vote in Washington, according to early results last night, with nearly 65 per cent of the votes counted.
