1.30 am London: Hillary Clinton is reported to have secured the required number of delegates to clinch the Democratic nomination, becoming the first woman to head a Presidential ticket for a major US political party.
The report, initially by the Associated Press, comes as voters in California, New Jersey and four other states are preparing to vote in party primaries on Tuesday. The AP writes:
Clinton, the former secretary of state, New York senator and first lady, reached the 2,383 delegates needed to become the presumptive Democratic nominee on Monday with a decisive weekend victory in Puerto Rico and a burst of last-minute support from superdelegates. Those are party officials and officeholders, many of them eager to wrap up the primary amid preference polls showing her in a tightening race with presumptive GOP nominee Donald Trump.
