Julia Hartley-Brewer and Caroline Lucas clashed over whether MPs should have consent training, as Julia branded the idea "offensive."
Several sexual harassment allegations have been made against MPs, leading to the resignation of Defence Secretary Michael Fallon. Theresa May has said she will take action to protect Westminster staff.
Green Party co-leader Caroline Lucas told Julia Hartley-Brewer: "I think we've come to the point where we ought to have some kind of consent training so that MPs are aware of what is and isn’t acceptable."
But Julia argued: "I find that frankly almost as offensive as asking university students to be taught not to rape.
"We’ve got a few people who harass women and then we’re going to accuse effectively all men of it."
Lucas hit back by saying "I’m not lumping all men into it or indeed all women into it.
"But just as you have teachers who will regularly on an annual basis have safeguarding training, then why could someone possibly object to the idea that having some consent training for all people who are in Parliament and indeed people in other walks of life should not be a bad thing."
She also added that both men and women should be involved in the training and "given that all of what we’re hearing now is not new, things haven’t changed to date we need to make things change very fast now.
Luca said: "I’m not saying [harassment] isn't happening in smaller businesses. Probably it is, given that we live in a patriarchal society in which sexism is pretty endemic."
Julia said "have you noticed who the Prime Minister is right now?" Pointing out several other women in positions of power and said she "didn’t get that memo" about being in a patriarchal society.
