One happy couple will be remembering the Pride in London parade on Saturday (June 25) for years to come, as footage from Ben May and the Met LGBT Network caught the moment a police officer broke ranks to propose in front of thousands.

The officer, who appears to have been on duty at the time, can be seen asking his boyfriend to marry him as festival-goers set off confetti and cheered in the background.

Fellow officers taking part in the parade stood in unison during the romantic proposal, which ended with a resounding "yes" and an enormous applause from the crowd.

In the video, which was shot outside Hamleys in Regent Street, the policeman holds the hands of his shocked partner and pops the question.

Thousands of people erupted upon the acceptance... But the happy couple didn't pause to celebrate for too long, as the officer soon joined the rest of the force and marched away in the parade.

The surprise proposal at Pride in London

The Met LGBT Network published an image of the heartwarming moment, but they weren't the only couple to get engaged during the event.

Soon after, the group posted another engagement photo of a different couple, with the caption "He said yes!"

The second loved-up duo appear to both be in the police force, and were photographed as one of the officers offers the other a ring.

A second proposal took place during the parade

The parade is not only London's biggest one-day event of the year, but is also one of the largest LGBT+ celebrations in the world, this year attracting thousands of visitors.

The parade began at 1pm in the West End and ended at Whitehall, making its way along Regent Street during the route, and going past Oxford Circus, Piccadilly Circus and Charing Cross underground stations.
