Former One Direction star Liam Payne has died at 31.   Payne had been in the limelight since 14 and formed One Direction at 16 as part of reality show X Factor. With the band, his rise to fame was swift, and they became one of the most successful pop groups worldwide.     But some former X Factor contestants have remarked about a lack of support while on the show, something about which Dean Piper, former showbiz columnist at the Mirror, tells Niall Paterson, "upon reflection, I'm sure that there's a lot of people that look back on those times that think 'God, we didn't really look after them at all'."     Our arts and entertainment editor Claire Gregory also joins Niall to talk about Liam Payne’s story and discuss the challenges of fame. Producer: Emma Rae Woodhouse Editor: Philly Beaumont
