Captured on Camera: Three British soldiers faint during royal parade in London heat

At least three guardsmen fainted in the heat during a military parade as temperatures in the UK soared to 30C (86F) for the first time this year, according to a report in leading British newspaper The Guardian.

The event at Horse Guards Parade in central London on Saturday was a rehearsal for trooping the colour and was reviewed by Prince William. Afterwards, the Prince tweeted that the troops had done “a really good job” in difficult conditions.

The soldiers were wearing woollen tunics and bearskin hats as a heat wave swept across London. The UK Health Security Agency has issued a hot weather alert for South England.

The event was a rehearsal for Trooping the Colour, an annual military parade held each June to mark the monarch’s official birthday. King Charles III will oversee the ceremony on June 17
