A Cavalry Guard fainted on the Mall in London during rehearsals Sunday amid the arrival of the first heatwave of the year.
The guard is thought to have passed out during a procession rehearsal for a state visit of the Emperor and Empress of Japan.
Photographs show the guard lying face down on the ground surrounded by onlookers before he is assisted by a fellow guard.
WHY HE PASSED OUT
It comes as health warnings were activated across England today as summer finally arrived with the first heatwave of the year and temperatures soaring to 31C (88F) this week.
The yellow heat health alert was issued by the UK Health Security Agency and Met Office for most of England, with all but the North East included in the warning.
The alert came into force Sunday morning as forecasters said the country would see mostly dry weather with ‘plenty of sunny spells’ and a maximum of 28C (82F).
