English indie rock band Blaenavon was to be a headlining act on the Festival Republic Stage, but on 20 June pulled out due to 'on-going health issues'. Crystal Fighters was announced as their replacement. G Flip, who was also due to perform on the Festival Republic Stage, also pulled out of the festivals for unknown reasons. UK drill rapper Loski has also been removed from the line-up. This may be because the rapper was arrested for being in possession with a firearm. Fellow UK drill rapper Unknown T was also removed after he was charged with murder and violent disorder after allegedly stabbing 20-year-old Steven Narvaez-Jara during a party. Geko was also supposed to perform on Radio 1Xtra Stage. It is unknown why he was removed. Brunswick who was also due to play on the Radio 1 Stage last year, was pulled from the line up again this year for unknown reasons. Two days before his performance at Leeds, Lil Uzi Vert pulled out of the festival for 'unforeseen circumstances'. Acts were pushed up, Yungblud and Mayday Parade swapped places, and SWMRS was upgraded from Festival Republic to the Main Stage. Comethazine and Masicka were replaced by DJ Grevious and M Huncho. King Princess was due to perform on the NME Stage, but had to pull out due to illness. Aitch was moved from the Radio 1Xtra tent, and took their slot. Drenge performed a secret slot on the BBC Introducing stage, Enter Shikari performed a secret acoustic slot on the same stage. This was the band's third set through the festival.
