Sanders wins Indiana Democratic primary: US networks

Senator Bernie Sanders has mounted a come-from-behind victory in Indiana's Democratic primary, denying the former secretary of state a feather in her cap as she seeks their party's presidential nomination.

Sanders, a self-declared democratic socialist, was ahead of Clinton by 53.2 per cent to 46.8 per cent with about three quarters of precincts reporting yesterday, although Clinton remained well ahead in the delegate battle for the nomination.
