Kenya's opposition has demanded early elections after President Mwai Kibaki dissolved his cabinet in response to a humiliating referendum defeat.
"This parliament is now discredited and the president must dissolve it to pave way for the people of Kenya to elect representatives with a new mandate," the main opposition and a dissident party from the ruling coalition said.
In a political first for Kenya, Mr Kibaki sacked all his ministers and assistant ministers late last night, saying he wanted to reorganise and unite a cabinet which has not met for months and been too divided to pass much-needed reforms.
The resounding rejection of his proposed constitution in Monday's poll was interpreted as a vote of no confidence in his government, leaving Mr Kibaki no option but to clear the political decks and show he still runs the country, analysts said.
Kenya has East Africa's largest economy and is viewed by the West as a linchpin of stability in turbulent east Africa.
