Britney Spears, Calvin Harris and The 1975 are among the artists confirmed to headline the Apple Music Festival 2016. The annual event, previously known as the iTunes Festival, will return to its home at the Roundhouse in Camden, north London in September.

Taking place between 18 and 30 September, other acts confirmed to perform include Elton John, Bastille, Robbie Williams, Chance the Rapper, Alicia Keys, OneRepublic and Canadian crooner Michael Bublé. Named Apple Music Festival 10, the event will celebrate its 10th anniversary this year.

Spears, who is preparing to release her ninth studio album Glory on 26 August, said in a statement about her upcoming performance: "I'm so excited to go back to London, which is a special place for me to visit, and I'm really looking forward to performing at the Apple Music Festival.

She added: "It's also their 10th birthday. It's going to be a great party." The Make Me singer last performed in the UK five years ago on her Femme Fatale tour in 2011.

Apple Music's vice-president of international content Oliver Schusser noted the "legacy" of the festival over the last decade, stating: "Over the past decade the festival has brought the biggest and best artists from all over the world to London and into the homes of millions of music fans. This year's Apple Music Festival builds on that incredible legacy and we couldn't be more excited to have another amazing line-up to celebrate our tenth birthday."

Fans in the UK will be able to obtain tickets for the festival through a ballot-only service on the Apple Music website and through the DICE ticketing app. Those who aren't able to get their hands on the free tickets can watch the performances streamed live on Apple Music.

The festival has always attracted high-profile performers over the last 10 years. Previous notable headliners include Amy Winehouse, Adele, One Direction, Paul McCartney, Oasis, Lady Gaga, Katy Perry, John Legend, Usher and Florence And The Machine. Kanye West also made a surprise appearance when Mr Hudson performed in 2009.
