300,000 People Expected For Brighton Pride 2016
This years Brighton Pride could see around 300,000 people celebrating in Brighton and Hove.
The brightly coloured, music filled procession has made it way around the city.
Sarah Tijou describes what it's like for Heart:
The city has been buzzing for the last couple of days as people make their way for the celebrations.
We're told security has been ramped up after recent attacks in Orlando and Nice but the threat level is moderate at the moment, which is lower than the national alert currently.
However we are being asked to be vigilant and sensible.
Paul Kemp is the Managing Director of Pride.
