Spice Girls selling out venues, but what's left of girl power?

This weekend Spice Girls began their reunion tour with a string of dates, including three nights at Wembley already sold out. UK and Ireland tour features Melanie Brown, Emma Bunton, Geri Horner and Melanie Chisholm, better known as Scary, Baby, Ginger and Sporty Spice, without Victoria "Posh Spice" Beckham. BBC questions "how can we explain the Spice Girls' influence two decades on, and where does Girl Power fit into a post-MeToo world?".
