The allegations of rape on 'Married at First Sight UK' have prompted Ofcom to investigate Channel 4's welfare practices after a BBC Panorama report revealed that two women were raped during filming, and a third experienced a non-consensual act. Channel 4 admitted prior knowledge of some allegations and has since removed all episodes from its streaming service. MPs have expressed concern over the handling of these allegations, and Ofcom is reviewing the situation to determine if regulatory action is needed.
