UEFA has stopped Dutch supporters from bringing rainbow flags into the official fan zone in Budapest ahead of the Euro 2020 round-of-16 tie between Netherlands and Czech Republic on Sunday.

A spokesperson for the KNVB confirmed to ESPN Netherlands that security guards asked fans with rainbow flags to hand them over at UEFA’s request.

UEFA will only allow national flags with the country’s colours into the fan zone and the Puskas Arena where the game will take place.

Dutch supporters decided to bring rainbow flags to Budapest in protest of a law passed by Hungarian lawmakers last week that prohibits sharing with minors any content portraying homosexuality or sex reassignment.

The law has been denounced as anti-LGBT discrimination by human rights groups, who say it links homosexuality with pedaphilia.

UEFA is investigating allegations of racist and homophobic chanting in the Puskas Arena during France’s 2-2 Group F draw with Portugal on Wednesday.

That game took place on the same day as Hungary’s encounter with Germany in Munich, when UEFA rejected a request for the Allianz Arena to be lit in rainbow colours due to its insistence that it would be a political act against new rules introduced by Hungary’s government.

Netherlands coach Frank de Boer confirmed captain Georginio Wijnaldum has said will wear a rainbow armband bearing the phrase “One Love” during Sunday’s Euro 2020 clash.
