Journalist Owen Jones stormed off a live newspaper review on Sky News after the show's presenter refused to describe the Orlando nightclub shooting as an attack on gay people.

The 31-year-old said he could not understand why the massacre at a gay nightclub in Florida that left at least 50 people dead was not being described as "the worst atrocity committed against LGBT people in the western world for generations”.

He clashed with Sky News Press Preview host Mark Longhurst and co-guest Julia Hartley-Brewer over the gunman's motives and whether or not the deadliest mass shooting in US history should be called a homophobic attack, rather than a religiously-motivated assault.

After several minutes of noticeable on-air tension on Sunday night, an exasperated Jones took off his microphone and walked off the set, saying: "I'm going home."
