Travel company Tui has ended its sponsorship of the UK and Australian editions of Married at First Sight on Channel 4 following allegations of rape and sexual misconduct involving contestants on the show.

A recent BBC Panorama investigation featured claims from two anonymous women who said they were raped by their on-screen husbands.

A third woman, Shona Manderson, also accused her on-screen partner of sexual misconduct.

All three men have denied the allegations.

Married at First Sight is a reality programme in which singles are paired by relationship experts and legally “married” after meeting for the first time on their wedding day.

A spokesperson for Tui UK and Ireland said, “Following the broadcast of the Panorama programme and discussion with Channel 4, we have taken the decision to end our sponsorship of Married at First Sight.”

A Channel 4 spokesperson said, “We’d like to thank Tui for being a valued sponsor of the programme. We look forward to discussing future partnerships.”

The broadcaster also said on Thursday that a Married at First Sight spin-off remains in pre-production.

It announced the launch of Second Marriage at First Sight in February, a new format designed to bring together contestants from both the UK and Australian versions of the show for a second chance at finding love.

“Whilst we’re in pre-production, we’ve not yet begun filming on Second Marriage at First Sight,” the spokesperson said. “Any findings from our review will be incorporated into the production.”
