Hillary Clinton called on Bernie Sanders on Sunday to help “unify the Democratic Party” after Tuesday’s primaries in California and New Jersey when she is expected in effect to clinch the nomination. With Mr Sanders insisting he will carry on his campaign until the party’s July convention, Mrs Clinton said Tuesday’s results would show she had “decisively won” the popular vote and the contest for pledged delegates.

“I’m going to do everything I can to reach out to try to unify the Democratic Party, and I expect Senator Sanders to do the same,” she told CNN on Sunday.

The two candidates were sparring ahead of what is likely to be the decisive week in a Democratic nominating contest that has been much longer and more contentious than most party leaders had predicted.
