A guardsman has collapsed during the Trooping of the Colour parade, part of the Queen's 90th birthday celebrations.
The event took place on Horse Guards Parade in central London.
While unidentified soldier's comrades remained still, he was soon attended to by officials and stretchered off the parade ground.
The soldiers wear a heavy uniform and a bearskin ‘Busby’ hat, which is thought to have contributed towards the collapse, in addition to the warm temperatures.
The hats have been worn in the British army since the 1830s.
In January, the Daily Mirror revealed that Ministry of Defence (MoD) spending on the hats – which cost £1,224 each - has increased dramatically in recent years.
The MoD spent £149,379 on 122 of the the hats at the taxpayer’s expense in 2015, the newspaper reported.
There have been celebrations throughout the weekend. On Friday, a member of the RAF collapsed while waiting outside St Paul’s cathedral for a service of the Queen.
