Ofcom has opened an investigation into Channel 4’s Married at First Sight UK following complaints related to fairness and privacy, according to multiple reports. The media regulator says it is looking into an unspecified complaint about the reality TV series. BBC and other outlets report that the probe comes amid controversy surrounding allegations made in connection with the show. BBC News points to an earlier Panorama report, broadcast in May, in which two women alleged rape; the men involved deny the allegations.

Deadline adds detail on how the regulator’s inquiry has been framed, saying that Ofcom’s group director of broadcast told British lawmakers Ofcom would examine an “advance copy” of Channel 4’s review into welfare on the programme and would urgently consider whether any regulatory action is necessary. The Evening Standard and The Independent similarly describe the investigation as relating to a complaint rather than a final ruling.

Overall, sources agree that Ofcom is examining the programme after receiving complaints, while Channel 4 has conducted a review addressing welfare concerns.
