Seven European selections had said they intended to have their captain wear a "One Love" rainbow armband but finally gave up, Fifa having threatened them with sporting sanctions.
Britain's Sports Minister Stuart Andrew announced he would wear it on Tuesday against England-Wales, two of seven selections who waived.
The English fan group "3LionsPride", which represents LGBT+ supporters, decided before this World Cup that its members would not travel to Qatar.
"These matches should be a celebration for all the fans, but unfortunately a lot of them feel that's not the case. It's not a tournament for them. They felt they couldn't to be part of it and it is not acceptable", regretted Stuart Andrew.
It will not be a first at the World Cup as German Interior Minister Nancy Faeser, in charge of sports, wore it next to Fifa President Gianni Infantino during Germany's 2-1 defeat against Japan last Wednesday.
The Belgian Minister of Foreign Affairs, Hadja Lahbib, did the same during the victory of the Red Devils against Canada in Qatar (2-1).
