Pakistan's top court has disqualified Prime Minister Yousuf Raza Gilani from holding office, two months after convicting him of contempt of court.
The Supreme Court ruled he had "ceased to be the prime minister of Pakistan".
In April, the Supreme Court convicted Mr Gilani of failing to pursue corruption charges against President Asif Ali Zardari.
The legal case is part of a bitter feud between Pakistan's civilian government and the judiciary.
In April, Mr Gilani was given only a token sentence and spared a jail term.
Tuesday's court ruling disqualified him from office and from parliament.
