ANC Women's League president Angie Motshekga has criticised the "sexist and racist" insults of Cosatu members towards DA leader Helen Zille and parliamentary leader Lindiwe Mazibuko.
Cosatu members said during Tuesday's DA protest in Johannesburg over a youth wage subsidy that they wanted to "strip Zille naked", and they called Mazibuko "the madam's sidekick".
Several female Democratic Alliance supporters who took part in the march were injured as a result of rough treatment by Cosatu men.
Motshekga told Beeld that the DA had provoked Cosatu but that their members should not have behaved in such a militant fashion.
She said it would have been better for them to simply accept the memorandum.
