The action has led to punishment from UEFA and condemnation from a long list of ex-players, so why is it done?
England's run to the final of Euro 2020 captured the imagination of the English public, with Raheem Sterling and Harry Kane inspiring a new generation of supporters.
However, the behaviour of some of the Three Lions supporters - particularly the booing of national anthems - took the sheen off, leading to words of condemnation. The anthems of Scotland, Germany and Denmark were subjected to boos and jeers when England lined up against them, but why?
Goal takes a look at the reasons and the response to the booing of the anthems.
