Belgium’s captain will wear rainbow colours on his armband at the European Championship on Sunday and the country’s football association (KBVB) is considering further ways to show solidarity with the LGBTQ movement.

The KBVB criticised Uefa’s refusal for the Munich stadium to be lit in rainbow colours for Germany’s Euro match against Hungary on Wednesday in protest against an anti-LGBTQ law in Hungary.

“We totally disagree with the Uefa decision and are probably going to play on Sunday with a rainbow band,” spokesman Stefan van Loock said on Wednesday. “Uefa should have allowed the rainbow colours to be displayed at the German stadium.”

Munich mayor Dieter Reiter wanted to highlight legislation in Hungary banning school materials deemed to promote homosexuality and gender change and restricting the media from showing such content in programmes accessible to minors. The Allianz Arena is configured to allow the exterior and roofing to be lit up in colours but Uefa declined the request, instead offering alternative dates.

A large banner in rainbow colours, together with the Belgian association’s badge, was flown at the entrance to the team’s training camp in Tubizeon Wednesday.
