The Prince and Princess of Wales were among the senior royals to join the King and Queen to kick off VE Day commemorations.
Prince William and Kate, along with their children, Prince George, 11, Princess Charlotte, ten, and Prince Louis, seven, watched the military procession from the Queen Victoria Memorial, outside Buckingham Palace, alongside the Duke and Duchess of Edinburgh, the Princess Royal and Sir Tim Laurence and the Duke of Kent.
The three young royals were seen engaging with the veterans who were seated alongside them, and waving as the military procession passed by.
At one time, William appeared to be explaining the different drummers to his kids, with Louis sweetly keeping his father in check, as he brushed tree pollen off the Prince's jacket.
After the procession, the royals gathered on the palace balcony to watch the Red Arrows lead a spectacular flypast with historic and current military aircraft.
The King and Queen then hosted a tea party reception for around 50 veterans and members of the Second World War generation at the palace.
Guests included British and Commonwealth Armed Forces veterans and women's Royal Navy Wrens, as well as the same royal family members and Sir Keir.
Prince George was a surprise addition at the gathering as he joined William and Kate to speak with veterans during the reception.
VE Day celebrates the day Britain and its Allies formally accepted Nazi Germany's unconditional surrender during the Second World War.

Procession and flypast route
The military procession started from Parliament Square in London from 12pm, travelling along Whitehall and The Mall, finishing at the Queen Victoria Memorial.
The procession featured an impressive display of pageantry by Regiments of the Household Division and Kings Troop Royal Horse Artillery.
The flypast included the Red Arrows, which saw them leave streams of red, white and blue, as they soared over central London.

The aircraft then dispersed over Buckinghamshire, Berkshire and Oxfordshire.
