Pride events have been largely cancelled in Europe this year due to coronavirus restrictions, but traditional marches have been replaced by online celebrations.
The international organization Global Pride is live stream of a 24-hour marathon presented by singer and drag queen Todrick Hall, former american idol contestant.
The event, which began at 6am London time, also features singers Kesha and Ava Max, as well as Carlos Alvarado, president of Costa Rica, who has just legalized gay marriage.
Organizers hope that this online format will enable a more diverse audience than usual in dozens of countries where homosexuality remains illegal and punishable by law.
UK Prime Minister Boris Johnson has joined the virtual celebrations by sending his best wishes to the LGBT community via Twitter.
In France, where the Paris Pride March has been postponed to November 7, gay magazine Têtu is broadcasting live on its website an event called Fièr.es et Têtu, with several guests, DJs and round tables.
In Berlin, hundreds took to the streets to protest discrimination against LGBT+ communities, despite the cancellation of the local Pride event.
Participants marched from Nollendorfplatz in the Schoeneberg district via Potsdamer Platz to Alexanderplatz.
Most of them complied with coronavirus restrictions, such as social distancing and the use of facial coverings.
This year marks the 50th anniversary of Pride.
Pride arose from the Stonewall riots of 1969, which followed a police raid at the Stonewall Inn in Greenwich Village, New York, one of the many lesbian and gay bars in the area.
A year later, on June 28, 1970, the first Pride March was held to mark the event in New York.
Then the Pride marches began in June and July in cities and cities around the world.
