Swapo Party MP Salomon April has called on lawmakers to uphold the decorum of the National Assembly and follow parliamentary rules when raising grievances.

The call followed last Wednesday's disorder that forced the sitting to adjourn early.

Deputy Speaker of the National Assembly Phillipus Katamelo says no law or parliamentary rule can fully regulate the moral conduct of members.

Katamelo emphasised that ethical behaviour ultimately depends on the consciences of individual lawmakers.
