Two women were reportedly removed from a plane at Heathrow Airport when a fight broke out over a Make America Great Again (MAGA) cap.
According to The Sun, the American passengers started arguing when one asked the other to remove the red hat – worn by supporters of Donald Trump – as they waited to board the flight in Terminal 5.
The woman wearing the cap refused, at which point punches were exchanged and the pair were later escorted off the flight, the newspaper said.
The Metropolitan Police told Sky News that officers at the airport were called to an incident shortly after 12.45pm on Monday.
“A woman in her 40s and a woman in her 60s made counter allegations of affray,” the force said.
