Five top contenders emerge in Harris VP hunt

Kamala Harris will begin a US tour with her new running mate next week, indicating that she is likely days away from announcing her choice.

The pool of candidates for Democratic vice-president has been narrowed to a group of five, according to CBS, the BBC's US partner.

A decision is required before the Democratic National Convention, which starts on 19 August in Chicago, preceding the November presidential election.

Once Ms Harris's running mate is announced, the two are expected to tour the battleground states.
