In the United States, Hillary Clinton has reached the number of delegates needed to clinch the Democratic presidential nomination. According to media reports Mrs Clinton, a former Secretary of State, reached the 2,383 delegates needed to become the presumptive Democratic nominee with a decisive weekend victory in Puerto Rico and a last-minute support from superdelegates.

She has 1,812 pledged delegates won in primaries and caucuses. The former first US lady also has the support of 571 superdelegates, according to an Associated Press count. Now, Mrs Clinton is on course to become the first woman to head a major US party ticket.

But the campaign of her rival, Bernie Sanders, vowed to keep up the fight, saying it was wrong to count the votes of superdelegates before they actually cast ballots at the Democratic National Convention in July in Philadelphia. In a statement, the campaign team of Sanders said, their job from now until the convention is to convince those superdelegates that Bernie is by far the strongest candidate against Donald Trump.
