The clean-up has begun after riots erupted on the streets of the Hungarian capital, Budapest, between police and protesters.About 100,000 people rallied to demand Hungary's Socialist prime minister Ferenc Gyurcsany resign.Fighting flared when protesters tried to free one of their leaders who police say led the storming of state television in September.Water cannons and teargas were used to clear the streets of several thousand mostly far-right radicals who threw stones at police.Unlike the clashes in September and October of last year, in which 800 police and demonstrators were injured, Thursday's violence was confined to fringe groups.The rioters say Mr Gyurcsany's government has broken campaign promises by hiking taxes and cutting spending since winning elections last April.A leaked tape in which Mr Gyurcsany admitted he had lied about the budget and the police action last October has also reminded people of the communist roots of the Socialists.© Independent Television News Limited 2007.
