Miss Universe contestants walk out after organiser berates Miss Mexico

Several contestants have walked out of a Miss Universe event after an official from host nation Thailand publicly berated Miss Mexico in a tense confrontation.

At a pre-pageant ceremony, Miss Universe Thailand director Nawat Itsaragrisil told off Fatima Bosch in front of dozens of contestants for failing to post promotional content.

When she objected, Mr Nawat called security and threatened to disqualify those supporting her. Ms Bosch then left the room and others joined her in solidarity.

Video of the incident, which was live streamed, has been shared online. The Miss Universe Organisation (MUO) has condemned Mr Nawat's "malicious" behaviour, for which he has since apologised.

The Miss Universe contestants, who are the winners of national pageants in their home countries, attended Tuesday's event in their sashes and gowns.

Some can be heard shouting back at Mr Nawat in the video, after he raises his voice to reprimand Ms Bosch and repeatedly tells her to stop talking.

As many of them stand to show support, Mr Nawat says: "If anyone wants to continue the contest, sit down. If you step out, the rest of the girls continue."

Despite this, the majority of the women in the video appear standing, with several heading towards the door.

After leaving the event on Tuesday, Ms Bosch told the press the 60-year-old executive was "not respectful" and said he had called her "dumb".

Mr Nawat has disputed this, claiming his words had been misunderstood.
