Watch the moment Lee Anderson was left flabbergasted after a GB News guest refused to support a ban on cousin marriage.
Political commentator Fahima Mohamed insisted the argument to outlaw first-cousin marriage in the interest of children's health was "inconsistent".
She argued there are greater matters to address when it comes to risks to children instead of "demonising" groups, citing FASD (Fetal Alcohol Spectrum Disorder) as an example.
But Lee accused his guest of deploying "what-about-ery" in the debate.
Discussion over the controversial practice has been reignited after Labour was accused of supporting the practice when MPs were told to block the legislation, tabled by Tory MP Richard Holden.
