The owners of Leicester City Football Club are reportedly being sued for £323m over money owed to the Thai government.
A criminal court in Bangkok accepted the case against King Power International on Monday, according to Reuters news agency.
The case is also being brought against executives of state-owned Airports of Thailand (AOT), Reuters says.

The BBC has contacted Leicester City FC, King Power and AOT for comment.
The lawsuit accuses King Power of failing to pay the Thai government 14 billion baht (£323m) from the operation of a duty-free franchise it was awarded in 2006.
At a hearing on Monday, the Central Criminal Court in Bangkok accepted the case and said it would now hear from witnesses in February next year.
The action against King Power, owned by Vichai Srivaddhanaprabha and his family, was initially filed in July.

This case almost certainly goes back to the time that the airport concessions were given out when the main international airport in Bangkok was being built.
Unravelling the complications of the contract and the concessions is likely to turn out to be a long, drawn out affair, as have been other such cases in Thailand.
There have been many cases in recent years that concern Thai billionaires and millionaires, none of whom have ended up in prison.
