Today’s rehearsal was for a state visit by the Emperor and Empress of Japan this week.
Tourists viewing the rehearsal in the shade behind a fence can be seen watching the scene unfold.
London was basking in sunshine today with Heathrow recording 25C at midday, according to the Met Office.
It comes as the mercury is set to rise higher in the upcoming days, with figures potentially reaching up to 32C in parts by Thursday.
A yellow heat health alert has been issued by the UK Health Security Agency (UKHSA) and Met Office for most of England.
Forecasters have warned of a likely “increase in mortality across the population” from today until Thursday.
The heat alerts will be in force for every region of England except the north east, which is covered by a green alert.
The Ministry of Defence has been approached for comment.
Met Office’s top hot weather tips
THE top ways to stay safe when the heat arrives, according to the Met Office.
Look out for those who may struggle to keep themselves cool and hydrated such as the elderly with underlying conditions or live alone.
If you live alone, ask a relative or friend to phone to check that you are not having difficulties during periods of extreme heat.
Stay cool indoors – Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors.
If going outdoors, use cool spaces considerately.
Drink plenty of fluids and avoid excess alcohol.
Never leave anyone in a closed, parked vehicle, especially infants, young children or animals.
Try to keep out of the sun between 11am to 3pm, when the UV rays are strongest.
Walk in the shade, apply sunscreen and wear a wide-brimmed hat, if you have to go out in the heat.
Avoid physical exertion in the hottest parts of the day.
Make sure you take water with you, if you are travelling.
Check the latest weather forecast and temperature warnings – you can find these on TV, radio, mobile app or website.
During warm weather going for a swim can provide much welcomed relief. If you are going into open water to cool down, take care and follow local safety advice.
