Amazing Thailand
Leicester City manager Nigel Pearson, whose son James was one of the three players shown in the video, appears in front of the the Tourism Thailand slogan

The Thai owners of Leicester City are facing increasing pressure to address a leaked sex tape in which three of the team's players appeared to use racial slurs while engaging in an orgy with sex workers on a post-season tour.

Father and son billionaires Vichai and Aiyawatt Srivaddhanaprabha, the owners of Leicester City and Thailand's leading travel retail group King Power International, have come under scathing criticism for their response to the sex tape, which was obtained by the Sunday Mirror.

In the sexually explicit video, Leicester City players James Pearson, Tom Hopper and Adam Smith are seen in a variety of sexual positions with the Thai women.

Off camera one of the men refers to a girl as a "slit eye", while Hopper, 22, describes another as "minging".

James Pearson is the son of the current Leicester City manager Nigel Pearson.

The Leicester squad members apologised for the video on 31 May and the players have been sent home. However pressure has started to build in Thailand for the team's owners to follow suit.

In a scathing editorial, the Bangkok Post said King Power and the Tourism Authority of Thailand, which also sponsors the team, should "examine their role in this degrading incident".

The English-language daily said: "Mr Vichai and Mr Aiyawatt have a special duty to fans of the team and all Thais, to explain and deal with the behaviour of their employees."

It added that Thailand's tourism authority needed to consider its connection with the team.

The Bangkok Post pointed to the irony of having 'Amazing Thailand' – the official slogan of the authority – emblazoned on the back of the players' jerseys. It also demanded a more substantive apology from all parties involved in the scandal.

British fans of Leicester City have been equally critical of the players' actions, with one fan forum saying behaviour was "disgusting and inexcusable".They added it was "exactly the sort of stuff that gives British tourists a bad name when we go abroad".
