Henrik Klackenberg works as a state herald at the National Archives, and is responsible for issues concerning, among other things, the use of the Swedish flag.
According to him, there are regulations on how the flag may be used, for example, it may not be "provided with additional letters or marks".
Another law states that the flag may not be used in business activities.
According to Henrik Klackenberg, Aftonbladet commits a trampling when they market themselves during football matches by connecting the Swedish flag with Sportbladet.
- They have distorted the flag, he says.
Therese Stalén, Aftonbladet's marketing manager, sees no problem with the flag.
- As one of the Football Association's partners, we have produced this flag to be part of and contribute to the wonderful atmosphere at Sweden's home matches, we think that the message Cheers Sweden is something everyone who is at the match can stand behind, she says.
