Two women have reported being removed from a plane at London Heathrow Airport after a fight broke out.

It's understood the fight broke out because the two American women were wearing Make America Great Again (MAGA) caps.

The passengers were asked to remove their caps by a fellow passenger on board the flight leading to a physical encounter.

As reported by The Sun, the flight was from Heathrow's Terminal 5, and the plane headed to Texas in the USA.

Passengers removed from Heathrow flight for MAGA hats

The outlet further reported that when the women refused to remove the MAGA hats, punches were exchanged leading to the pair being removed from the Heathrow flight.

Speaking to Sky News, the Metropolitan Police said the incident took place after 12.45pm on Monday.

They added: "A woman in her 40s and a woman in her 60s made counter allegations of affray."

MAGA hats are worn in support of Donald Trump, who coined the phrase in 2016 as part of his first presidential campaign which saw him take a seat in the White House.

Trump is currently running again for the Republican and hopes to win the White House back from the Democrats.

US Vice President Kamala Harris is running for the Democratic seat with the election taking place on Tuesday, November 5 and is expected to be the tightest election in modern history.
