Cape Town - DA leader Mmusi Maimane has called on all 72 Cabinet ministers and their deputies to recuse themselves from voting in the motion of no confidence in President Jacob Zuma.
Maimane, on Monday, said he had written to the ministers to make the request on the grounds that it was a direct conflict of interest.
He said if ministers and deputies voted it would be contrary to section 96(2)(b) of the Constitution, which stated that they may not expose themselves to any situation involving a risk of conflict of interest between their official responsibilities and private interests.
"It is clear that there is a glaring conflict of interest between their official responsibilities and their private interests – in other words whether they keep their jobs or not.
"Each of the 72 ministers and deputy ministers must be excluded from the vote for this reason," Maimane said.
However, the ANC chief whips office said the request by the DA leader was just "political posturing".
"It's just a political statement, political posturing which has absolutely no substance constitutionally or legally," spokesperson Moloto Mothapo said.
"I don't think any right thinking person will even entertain such [a request]."
Maimane said he had also written to National Assembly Speaker Baleka Mbete, asking that voting on the motion of no confidence be done via secret ballot.
This was to ensure that MPs were not threatened with fear of internal persecution and were able to "vote with their conscience", he said.
Mbete's office said she was yet to receive the letter from Maimane.
