Twitter user Hannah Eachus also captured some beautiful images of the two.

The short but sweet proposal saw the officer say yes and the two shared an embrace as crowds around cheered for them.

It was the 45th annual London Pride parade held and marked 50 years since decriminalisation of homosexuality in England and Wales.

Thousands of people lined the streets of London for the celebrations and walked down Oxford Street to Trafalgar Square.

Over 150 police officers joined the event, as well as people from the London Ambulance Service, London Fire Brigade and British Transport Police.

In 2016, two gay police officer couples got engaged.

PC Phil Adlem got down on one knee to propose to his partner Jonathan Sammons, while PC Sam Philpot separately popped the question to PC Martin Coughlan.

However, PC Adlem has since said that he was taken aback by hatred and abuse after the clip went viral.

He explained: “My smile did not last long as I continued reading. ‘Both should be hanged till death’, ‘Absolutely disgusting’ and ‘Don’t blame ISIS if they strike them!’.

“There were countless more, some with threats. A further hostile reaction at work from one of my colleagues and another from an old college friend was enough for me to wish I had never done it.”

Mayor of London Sadiq Khan was at the event, and he told PinkNews about the importance of fighting aginst discrimination using love.

Across the city buildings and companies celebrated Pride in their own way.

The Houses of Parliament, MI6 and Guildhall London were all illuminated with rainbow lights and flew the Pride flag.
