Sam Plant, Chief Legal Officer at Müller UK & Ireland, brings a refreshing mix of humility, insight and honesty to this episode of Lessons I Learned in Law. From risk-taking in legal advice to speaking up about gender inequality, Sam shares three candid lessons that challenge the status quo.

Leading the legal and compliance function across one of the UK’s best-known consumer brands—yoghurts, milk, desserts, and a vast B2B logistics network—Sam reflects on a career shaped as much by mistakes as by milestones. He explains why embracing the right kind of mistake can sharpen commercial judgement, and why lawyers who never get it wrong may be playing it too safe.

Sam also offers a counterpoint to the classic “say yes to everything” career advice. In his view, learning to say no—to roles, responsibilities, and scope creep—is essential for long-term success and team wellbeing.

In a standout third lesson, Sam shares how he became more aware of his own privilege and began advocating for gender equity in law and beyond. His honest reflections on male allyship, everyday bias, and building trust with women in the profession are as powerful as they are practical.
