Berlusconi had demanded those resignations in a show of solidarity ahead of a Senate vote to strip him of his seat because of his tax-fraud conviction and prison sentence.
But at least three of his five ministers in Premier Enrico Letta's government, where Berlusconi's Freedom People party is the main partner, said they would only reluctantly comply with that order because Berlusconi had picked them for their ministry posts.
"I thoroughly understand his (Berlusconi's) state of mind, but I cannot justify or share the strategy" that the ministers quit, said Health Minister Beatrice Lorenzin. Another close aide to Berlusconi, Reforms Minister Gaetano Quagliariello, said he would follow his conscience in the confidence vote.
Speaking by telephone to rank-and-file members of his part at a Naples rally, Berlusconi called for "elections as soon as possible" and boasted "we will win." But hours later, he suddenly took a softer tack.
"We know how to distinguish the real interests of the citizens," Berlusconi said, referring to himself and his lawmakers.
A Cabinet meeting Friday night was supposed to earmark the funds to avert the sales tax increase. But escalating tensions in the coalition over Friday's vote by a Senate committee on Berlusconi's seat dominated the session. The tax hike is set to go into effect on Tuesday.
