A proposed new law would deal with MPs who misled or lied to Parliament, such as former Chief Whip Tony Yengeni, National Council of Provinces Chairperson Naledi Pandor said on Friday.

There was currently no mechanism to discipline a member for lying to the House, although the issue could be dealt with by way of setting up an ad hoc committee, she told a parliamentary briefing.

However, the proposed Powers and Privileges of Parliament Act would deal with the issue of an MP misleading the House.

Pandor said she had yet to see a resolution from the National Assembly on the Yengeni question, and said the matter still required attention.

Among the priorities this year was to finalise the legislation on Parliament's powers and immunities, as well the financial administration and accountability of Parliament and the provincial legislatures.

Earlier this week, at an informal meeting of chief whips, it was decided that the issue of Yengeni lying to the National Assembly in a special statement to the House on March 28 last year, would be dealt with at their next meeting.

This is in addition to an inquiry by Parliament's ethics committee into his failure to disclose -- in the register of members' interests -- a discount of 47 percent on a luxury 4x4 vehicle from a company involved in the arms deal.

The ethics inquiry was suspended pending the outcome of his trial, and National Assembly Speaker Dr Frene Ginwala has called for it to be re-opened.

Yengeni was convicted of fraud last week after pleading guilty in terms of a plea agreement with the state. He was, in return, acquitted of corruption.

He will be sentenced on March 17.

In that statement to the National Assembly, Yengeni claimed he had legitimately purchased the vehicle. His protestations of innocence even resulted in a petition signed by ANC parliamentary staff supporting him and condemning the media.

Yengeni told the Assembly: "Its acquisition does not in any way amount to a gift or a donation, and therefore there was no interest to be declared."

The ANC national working committee is expected on Monday to decide Yengeni's future in Parliament, amid calls for him to resign or be fired by his party.
