Argentina's new president Eduardo Duhalde, the country's fifth leader in two weeks, said he will form a government of national unity to help deal with massive economic and social chaos. "My commitment from today is to finish with an economic model that has brought desperation to the vast majority of our people," Mr Duhalde told Congress after a special session elected him president until new elections in 2003. Thousands of protesting Argentines banged pots and pans during the new President's inauguration.
