Pride is an annual festival that celebrates LGBT+ (lesbian, gay, bisexual, transgender +) individuals, and is the biggest one-day event held in London annually.
Pride is seen as a time when LGBT+ people come together to celebrate and raise awareness of their community issues. There are usually many events in London across a chosen week, with the parade finishing the celebrations on the weekend.
Around 30,000 people took part in 2015 parade to wave their flags and show their support.
James Holt, director of communications for Pride in London said: "The theme of Pride in London this year is #NoFilter. This is all about campaigning for those people who have to live their lives with a filter, unable to be their true self.
"It also celebrates the progress we have made. For this day, for this moment, people in London can be free to be whoever they want to be."
The parade
This year, the parade will take place on Saturday June 25, from 1pm to 4.30pm.
The parade is a fun, colourful event in which organised groups walk through London with displays, banners and costumes. It is an inclusive, family-friendly event, and under-18s are welcome to watch.
The streets will be closed for the parade, and may get very busy; you can avoid this by sticking to less congested areas or getting there early. The event is free to watch.
The route
The parade route begins in Baker Street and leaves at 1pm. It turns left into Oxford Street, past Selfridges, Bond Street Underground Station, and John Lewis. At Oxford Circus it turns right into Regent Street and continues down to Piccadilly Circus.
From there it heads down Lower Regent Street and into Waterloo Place, then left into Pall Mall, heading right into Cockspur Street and across the south-western end of Trafalgar Square.
It then turns into Whitehall, before finishing at Whitehall Place.
