Hundreds of people have gathered in London and in other cities to mourn Liam Payne, as fans around the world grieved for the One Direction singer.

Directioners, as supporters of the massively successful boy band are known, left tributes in London, Glasgow, Paris, Sydney and New York this weekend as they celebrated the life of the 31-year-old.

He died on Wednesday (local time) after falling from a hotel balcony in Buenos Aires.

In London’s Kensington Gardens, grieving fans clapped and sang after gathering near a statue of Peter Pan, the fictional boy who never grew up created by JM Barrie.

The mourners, mostly young women, left heart-shaped balloons, photographs and flowers at the base of the statute, which sits next to a narrow path next to a waterway known as The Long Water.

Mindful of the crowds in the limited space, organisers asked those who attended to leave tributes then move away to allow others to approach the statue.

Fans Lauren Anderson and Natasha Bradley, both 23, said they wanted to be with others who shared their grief.

“Your parents, they don’t really understand how much [One Direction] really meant to you growing up,” Bradley said.

The vigils followed others outside the Casa Sur Hotel in the chic Palermo neighbourhood of Argentina’s capital immediately after Payne fell from his third-floor hotel room.

The four surviving members of One Direction issued a joint statement last week saying they were “completely devastated” by the death of their bandmate.

One Direction rose to worldwide popularity soon after the band was formed in 2010 from five young singers who auditioned for the British version of the TV talent show The X Factor.

The band broke up in 2016 after producing five albums that sold more than 70 million copies.
