An estimated 40,000 people joined Liverpool Pride on Saturday – double the number who turned up last year.
The festival, now in its second year, was held at the city’s waterfront, where it is thought around 35,000 people joined the celebrations.
A further 5,000 attended events in the gay quarter, Pride organisers said.
Around 2,500 people took part in the parade, which was led by the family of Michael Causer, the gay teenager who was killed in Liverpool in 2008.
Tommy McIlravey, the chair of Liverpool Pride, said: “It was an absolutely brilliant day, everything went to plan and we were even blessed with good weather. We didn’t think anything could top last year’s event but this surpassed our wildest dreams. We smashed last year’s attendance of 21,000 with 35,000 coming along to enjoy Pride this year, which was incredible, at one point, 20,000 people were on the festival site.
“The whole of Merseyside was represented, which is what the event is all about, people brought along their children and their grandparents, there was such a great mix of people. Having the festival at the Pier Head in front of the Liver Building proved a huge success and we’ve had fantastic feedback about the festival site and our wonderful programme of events.”
Until 2010, Liverpool was the only major UK city not to have a Pride festival.
