Democratic convention gets off to a rocky start

The Democratic convention has begun badly in Philadelphia as the chairwoman of the party’s national committee resigned over an email scandal.

It was a blow to Democratic presidential nominee, Hillary Clinton, who arrived in the city eager to show off a united party, after a tough campaign against Bernie Sanders.

Debbie Wasserman Schultz quit a few days after the publication of 19,000 hacked emails, which Sanders said confirmed his belief that the national party had favoured Clinton.
