Charges of treason against Zimbabwean opposition politician Roy Bennett have been dropped, and replaced with other allegations, his party says, BBC reporteed.
The new charge is conspiring to acquire weapons for the purpose of disrupting public services, the MDC said.
Mr Bennett, a deputy ministerial nominee, was arrested on Friday shortly before President Robert Mugabe swore in new ministers of the unity government.
His lawyer, Trust Maanda, said the treason case did not "hold water".
"The police must have realised that they had no leg to stand on," Mr Maanda told the AFP news agency.
But Mr Bennett remains in custody.
"Bennett is currently being interviewed by the police. He is now appearing in court on Monday facing fresh charges," Mr Maanda added.
There was no confirmation from the police or justice officials that the charges had been changed.
Mr Bennett, a member of Morgan Tsvangirai's Movement for Democratic Change (MDC), was picked by the party to be deputy agriculture minister.
