In one corner: the International Boxing Federation Iba, which defies Cas (Court of Arbitration for Sport) rulings and the International Olympic Committee (IOC) and which, through undemocratic rule, is about to get boxing kicked out of the Olympics.
In the other corner: a number of Western countries, including Sweden, that have been involved in starting a challenger federation (World Boxing) to save the sport remaining in the Olympics.
Sweden is one of several boxing nations boycotting the ongoing men's World Championship in Tashkent because Iba welcomes Russians and Belarusians, also without reservation.
Swedish twins in the World Cup
In response to the boycott, Iba has invited all boxers who want to join, and paid for the trip to Uzbekistan. Two Swedes have taken up the offer, twin brothers Adel and Adam Belalia, 25, who in the World Championships go up in the 67- and 75-kilo classes respectively. They have their roots in the Stockholm suburb of Hässelby.
"They no longer live in Sweden and don't have a license here. Still, they are under the Swedish flag in the World Cup, says Sjöholm.
"Several other countries also have boxers there that they have not approved. Iba is still playing a game, and it continues in an unpleasant way.
The Swedish Boxing Federation has written a letter of protest to Iba, led by Russian Umar Kremlev, to abdicate responsibility for the Swedes and hear how it could be that Swedes who do not have a license in Sweden are allowed to participate.
Since World Boxing (WB) was formed just under a month ago, Iba has broken off the sponsorship selections with Russian oil and gas giant Gazprom and formed an ad hoc committee to try to persuade the IOC to keep boxing on the Olympic program. Sjöholm does not believe they will succeed.
"Nothing has changed other than the termination of the Gazprom agreement. Iba still does not care about democratic rules of the game, it has clearly shown that when it has not cared about, for example, decisions in Cas (the arbitration court for sport), he says.
