The theme for this year’s Brighton Pride has been announced as “Gay Icons,” which organisers hope will inspire parade-goers to create costumes ranging from Lady Gaga to Alan Turing.

The celebrations will be held in Preston Park on Saturday 3 August, marking the 21st anniversary of the event.

Organisers said in a statement: “‘Gay Icons’ is the theme for 2013 placing emphasis on the vast array of Iconic LGBT figureheads, campaigners and popular celebrities that have shaped and advanced LGBT culture and the cause of equality throughout history.

“News of the theme should set sewing machines whirring and sequins flying all over the city as an expected deluge of Gagas, Monroes, Madonnas, Boy Georges and Freddie Mercurys plan their costumes for the event of the year.

“Other important icons to celebrate will be the likes of Oscar Wilde, Quentin Crisp and Alan Turing.”

Paul Kemp of Aeon Events said: “There are so many important and influential people for us to celebrate as a community. They range from the most spectacular and celebrated stars of stage, screen and music to those who have changed the lives of the LGBT community and furthered equality through politics and sheer bravery.”

The 2012 event, which had the theme “The United Colours of Pride”, drew a host of rainbow flag themed costumes and floats, which can be seen in the event photo gallery.
