The biscuit breaking politics of Mumsnet

Justine Roberts is the founder and CEO of Mumsnet, the UK’s largest online network for parents—and a surprising powerhouse in British political life. Since its launch in 2000, Mumsnet has grown from a niche forum into a digital force capable of shaping public debate, influencing party manifestos, and unnerving prime ministers. Politicians from across the spectrum have courted its users, recognising the site's unique reach into the hearts—and voting intentions—of middle Britain. Often underestimated, always influential, Justine Roberts has carved out a space where motherhood meets activism—and where difficult questions are the norm.
