The late Queen Elizabeth II even managed to join the celebrations.
Recalling the moment in 1985, Britain’s longest-reigning monarch said: "We were terrified of being recognised – so I pulled my uniform cap well down over my eyes.
"A Grenadier officer among our party of about 16 people said he refused to be seen in the company of another officer improperly dressed. So I had to put my cap on normally."
Rishi SunakPAMore than 380,000 British soldiers were killed in combat during the Second World War.
An additional 70,000 people died in the United Kingdom in its civilian death toll, including 40,000 in the seven-month period in which Germany bombarded Britain during the Blitz.
In a summary of the significance of VE Day, the Royal British Legion said: "After nearly six years of war Germany officially surrendered on 7 May 1945 and the conflict was finally over.
"The unconditional surrender came after Adolf Hitler took his own life on 30 April as the Allies surrounded Berlin, and was authorised by his successor Grand Admiral Karl Dönitz.
"News that the war in Europe had ended did not come as a surprise and had been anticipated back in Britain for some time as the Allies advanced on Germany."
