Johannesburg - The Scorpions are to give parliament a report this week on gifts received by Deputy President Jacob Zuma, the unit's spokesman, Sipho Ngwema, has said.

Parliament's ethics committee is to establish whether these have been disclosed in the register of members' interests.

The National Directorate of Public Prosecutions decided not to prosecute Zuma on allegations of corruption connected to the multibillion-rand arms deal.

Zuma pressed public prosecutions chief Bulelani Ngcuka again yesterday to take him to court if he had evidence that he had been involved in wrongdoing in relation to the arms deal.

After speaking at the first national congress of the SA Transport and Allied Workers' Union here, Zuma said Ngcuka's decision not to prosecute him was "not helping at all".

"It has almost been a trial by media, many adjectives have been used to describe me with information leaked from the Scorpions," he said.

Ngcuka said at the weekend that Zuma would not be prosecuted, although the investigating team had found evidence that there was a case for him to answer and recommended that he be charged.

The decision could be reviewed should fresh evidence be found, Ngcuka said.

Zuma said yesterday that he believed a prima facie case should be taken to court for a decision. The decision not to prosecute him "leaves suspicion", he said.  

He would not say whether he intended to sue Ngcuka or the Scorpions.

Zuma has repeatedly denied that an attempt was made to solicit a R500 000 bribe from Alain Thetard, the former southern African head of French arms company Thomson-CSF.

The United Democratic Movement has joined the Democratic Alliance in calling for Zuma's resignation.

"President Thabo Mbeki should protect the dignity of the presidency by asking Mr Zuma to step down," UDM leader Bantu Holomisa said. He said there was an emerging consensus that Zuma had not been cleared.

Holomisa said Mbeki should "understand that we are not only dealing here with criminal evidence and the question of reasonable doubt.

"The important thing is that damage is being done to the presidency and the country as a whole.

DA chief whip Douglas Gibson said Zuma should resign to protect the dignity of his office and "before there are further humiliations".

The leader of the African Christian Democratic Party, Kenneth Meshoe, said Zuma should prove his innocence or step down.
