``I present my irrevocable resignation because I cannot work with a corrupt and incompetent political leadership,'' Teta had said. The resignations came two days after Albanian Opposition leader and former president Sali Berisha told supporters in central Tirana to continue their fight to oust Nano.

Berisha firmly rejected appeals made on Friday by President Rexhep Meidani to all political groups not to hold open-air rallies until Albania had returned to normal life after serious clashes earlier this month between government forces and opposition supporters.

The Opposition leader, whom the government accuses of mounting an attempted coup, urged his supporters to demonstrate ``everyday across Albania until thecollapse of Nano's criminal regime.'' Berisha claims that Nano was behind the killing of his party's deputy leader, Azem Hajdari, on September 12.

The assassination sparked two days of rioting during which four people were killed and 80 wounded.
