A festive pop banquet with more big names than you can jingle your bells at, including Taylor Swift, Sam Smith and Take That.
A mind-boggling number of chart-conquering acts cram into The O2 for two hectic days of full-on pop mayhem. Limp pop-rockers OneRepublic head up Saturday's line-up, which also includes perennial manband favourites Take That (now a three-piece after the departure of Jason Orange), professionally cheeky-chap Olly Murs, U2-lite trio The Script, chart-topping violin-pop quartet Clean Bandit and upcoming boybands The Vamps and Union J.
Sunday is even bigger, with none other than Taylor Swift topping things off – expect a guest appearance by her BFF Ed Sheeran, second on the bill. D&B producers Sigma, Aussie teen-rockers 5 Seconds Of Summer, Afrobeats dude Fuse ODG, lung-busting motormouth Jessie J, sadsack soul man Sam Smith and new boyband Rixton round things off – phew.
