World Lethwei Federation

The World Lethwei Federation (WLF) (ကမ္ဘာ့လက်ဝှေ့အဖွဲချုပ်) was founded in 2019 as the international governing body for amateur and professional Lethwei. The WLF has the responsibility to sanction and support the growth of Lethwei worldwide outside of Myanmar, including enforcement of its traditions, rules and regulations.

History
In 2018, Danish businessman Andi Egeberg invited Lethwei world champion Dave Leduc and organized the first Lethwei seminar in the country of Denmark. In 2019, Egeberg established the Danish Lethwei Federation (Dansk Lethwei Forbund) and founded the World Lethwei Federation headquartered in Copenhagen. Operating as a member of the World Lethwei Federation, the Slovak Lethwei Association (Slovenská Lethwei Associácia) has supported the growth of the sport in Eastern Europe by sanctioning many Lethwei events in Slovakia. Due to the violent ruleset, Lethwei is difficult to sanction and is only legal in a few countries outside of Myanmar.

On November 7, 2020, in partnership with the Wyoming Combat Sports Commission, the WLF the sanctioned the first-ever Lethwei fight and the first Lethwei world championship fight in the United States. Dave Leduc defended his traditional Lethwei world title against the American Cyrus Washington in Cheyenne, Wyoming. In 2021, the Amateur Lethwei World Championship scheduled to be held August in Warsaw, Poland, was cancelled due to COVID-19 pandemic travelling restrictions. On October 29, 2022, the WLF sanctioned the first-ever Lethwei World championship in Europe. The match featured the Slovak Michal Kosik against the Canadian Daniel Lariviere in Brezno, Slovakia.

In 2023, the World Lethwei Federation selected Prom Samnang as the challenger for the openweight Lethwei World Championship against Dave Leduc because of his winning streak in Kun Khmer. The match was scheduled to take place on May 27, 2023, in Banska Bystrica, but was cancelled because Samnang was denied a Schengen visa to enter Slovakia.

On July 8, 2023, the WLF to unveiled its inaugural Red belt for the world title fight between Ivan Hatala and Artur Saladiak. "Boxing has the WBC Green belt, Lethwei has the WLF Red belt." said President Andi Egeberg. Saladiak defeated Hatala by TKO in the fourth round and became the WLF Lightweight champion.

MTLF controversy
In 2021, the Myanmar Traditional Lethwei Federation (MTLF) issued an official letter banning the Lethwei world champion Dave Leduc from competing under their federation for 2 years, because of provoking comments he made about Buakaw Banchamek and the sport of Muaythai. In a Facebook post, Leduc said that "the WLF is the most powerful, they have affiliated federations all across the world" and stated his intention to only compete in WLF sanctioned events from now on. He added: "There's two Federations in Lethwei: the WLF / World Lethwei Federation and the MTLF / Myanmar Lethwei Federation, who are just a bunch of old men from a community club that never liked me & I never liked them either. They made an “official letter” saying they ban me from their federation “for 2 years” Am I supposed to care? Not only do I not care, I will go further and say: I will never fight in their federation ever again."
