A documentary telling the story of the Spice Girls airs its first episode on Channel 4 tonight.

'Spice Girls: How Girl Power Changed Britain' marks 25 years since the group released their debut album, Spice.

Made up of Melanie Brown (‘Scary Spice’), Melanie Chisholm (‘Sporty Spice’), Emma Bunton (‘Baby Spice’), Geri Halliwell (‘Ginger Spice’) and Victoria Beckham (‘Posh Spice’), the group formed in 1994 and eventually became the best-selling girl group of all time.

Their debut single Wannabe was also released 25 years ago, which topped the charts in 37 countries and truly began their global success.

The documentary will look at their rise to fame using rarely seen archive footage and interviews.

In the first episode the group’s formation will be looked at, alongside their increasing stardom and what that meant for contemporary feminism.

Here’s how to watch all the episodes.
