You’d think as the son of the founder Richard Walker OBE could have walked straight into the top job at Iceland Foods - the supermarket empire his parents built from a tiny shop in North Shropshire. Instead, he spent years building his own property empire in Poland, determined to prove himself on his own terms.

But when his mother was diagnosed with early-onset Alzheimer's Richard decided it was time to be closer to the family unit and join the business, starting at the very bottom stacking shelves in London stores - the best year of his life, he claims.

Since then, he's transformed Iceland into one of Britain's most pioneering retailers, removing palm oil from all own-brand products, launching radical campaigns on plastic and food poverty, and proposing that low-risk offenders serve their sentences working in Iceland stores rather than taking up valuable space in prison. This is a masterclass in how to earn respect, and use business as a platform for change.

LESSONS YOU'LL LEARN:

Never ever ever ever give up - originally Richard’s father’s mantra that carried Iceland through countless crises. When kicked out of his own company, he started a rival chain that became his ticket back in. Tenacity isn't just admirable - it's essential.

Prove yourself from the bottom up - Richard spent a year stacking shelves to earn his right to lead. The privilege of family succession means nothing without the respect of 30,000 employees who need to see you're one of them.

There's a difference between delegation and abdication - leading 30,000 people requires trusting an amazing team while keeping your eye on the details. Effective leadership is knowing when to step back and when to dive in.

Get comfortable being uncomfortable - whether it's climbing Everest with failing eyesight, lying next to a dead body at 29,000 feet, or building a business from scratch in Poland where you don't speak the language, growth lives outside your comfort zone. Embrace the risk.

Appreciate what you already have - Chasing unicorns (like becoming an MP) can blind you to the platform you already possess. Richard realised Iceland gave him more power to drive change than any backbench seat ever could.
