Greek PM to go ahead with austerity plans amid protests

Greek unions have staged mass protests in the city of Thessaloniki against the government's austerity programme.

Prime Minister George Papandreou, who is attending a trade fair in the city, has said he is not going to give up on his government's plans.

The protests were largely peaceful but police used tear gas on a small group which broke away from the rally.
