US Presidential elections 2016: Hillary Clinton creates history, secures Democratic nomination says AP count

According to the US delegate counts released on Monday Hillary Clinton has clinche the Democratic nomination for US president after reaching the required number of delegates. The count puts Clinton on 2,383 and this makes her become the first female nominee for a major US political party.

Clinton reached the big threshold with a big win in Puerto Rico and a burst of last-minute support from superdelegates, to which rival Bernie Sanders said Mrs Clinton had not won as she was dependent on superdelegates who could not vote until July's party convention.

Now who are superdelegates? They are party insiders who can pledge their support for a candidate ahead of the convention but do not formally vote for them until the convention itself.

Hillary’s unprecedented rise to presumptive nominee arrived nearly eight years to the day after she conceded her first White House campaign to Barack Obama.

Shortly after the news broke, Clinton at an appearance in Long Beach, California said, “We are on the brink of a historic and unprecedented moment but we still have work to do.We have six elections tomorrow and we're going to fight hard for every single vote, especially right here in California.”

Clinton has 1,812 pledged delegates won in primaries and caucuses. She also has the support of 571 superdelegates, according to an Associated Press count.
