Hillary Clinton and Bernie Sanders have clashed over Wall Street and foreign policy, in the Democratic presidential candidates' first one-on-one debate.
Mrs Clinton cast him as an idealist who will not get things done and Mr Sanders accused her of being too tied to the establishment to achieve real change.
The TV debate in New Hampshire was their first since the Democratic race was whittled down to two this week.
Without a third person on stage, the policy differences were laid bare.
The former secretary of state said Bernie Sanders' proposals such as universal healthcare were too costly and unachievable
