The Mexican wave is at the centre of a new diplomatic row. Whitehall sources tell me the UK is pressing for a global code of conduct on sports traditions after a record-breaking attempt in Wembley sparked accusations of cultural appropriation.
It started with the Euro 2028 qualifier. England versus Poland. A group of fans in the lower tier began a coordinated wave. It circled the stadium three times. A new national record, they said. Social media erupted in celebration.
Then the backlash hit. Mexican officials were furious. The wave, they insisted, is theirs. Invented in the 1980s at the Estadio Universitario in Monterrey. It has a name, a history, a soul. Calling it a "Wembley Wave" was an act of cultural theft.
Downing Street was blindsided. Prime Minister's spokesman offered a careful response: "We respect all football traditions. We will look into the matter." That was three days ago. Now, I am told, the Foreign Office is drafting a memorandum.
The memo proposes a "Global Sports Heritage Protocol." It would require organisers to seek permission from the originating nation before attempting to set records with borrowed fan movements. No more Polish fans doing the Poznan without a nod to Lech. No more Viking clap without Norway's blessing.
Critics are furious. A senior backbencher told me this morning: "This is madness. The government is regulating football chants? Have they forgotten Brexit?" Another called it "gesture politics at its worst."
But the PM is wedged. The Mexican ambassador has formally complained. The World Football Association has expressed "concern." The Mayor of London, already at odds with No.10, saw an opportunity. He declared a "Love the Wave, Respect the Source" campaign. Flags will fly on the GLA building.
Privately, cabinet is split. The Culture Secretary thinks the whole thing is a joke. The Home Secretary sees a slippery slope. "Next they'll ban the conga," he was overheard saying.
The numbers tell a story. YouGov has the data. 34% of Britons think the wave is British. 21% think it's American. Only 8% credit Mexico. The rest don't care. But among under-30s, awareness of cultural borrowing is higher: 52% said they would support a formal apology to Mexico.
So the government is cornered. No majority. A by-election looming. And now a row about a stadium gimmick. Sources tell me the whips are worried. A handful of Labour MPs are tabling an Early Day Motion: "For the Respect of Global Sporting Traditions." It has no legal force, but it makes the news.
The Mexican wave record chase is still on. But now each attempt is scrutinised. At the next England game, stewards may intervene. The FA has issued a statement: "We await the Foreign Office guidance."
This is a story about symbols. Power. Who owns a gesture. It is also a story about a government so fragile, it trembles at a wave.
