Sustainability expert and professor Mike Berners-Lee argues that dishonesty in politics, business, and the media is one of the biggest barriers to tackling global crises like climate change, social inequality, and environmental destruction.

In this episode of Ways to Change the World, he talks to Krishnan Guru-Murthy about the need for a cultural shift where honesty is valued, and where deceit in public life carries real consequences. Without this, he warns, we risk making the world's biggest challenges even harder to solve.

Entrepreneur, investor, and former Dragon’s Den star Sara Davies has spent 20 years building businesses and helping others do the same. She started her company, Crafter’s Companion, while still at university and turned it into a global brand. But as she tells Krishnan Guru-Murthy, success isn’t just about strategy - it’s about mindset.

It’s a theme she explores in her latest book, The Six-Minute Entrepreneur, which distills the lessons of her own journey into advice for anyone looking to succeed.

In this episode of Ways to Change the World, she reflects on the challenges facing small businesses, what she’s learned from Dragon’s Den, and why the UK needs to celebrate its entrepreneurs more. As she steps away from the Den, she also shares what’s next for her and why she remains deeply passionate about backing businesses that make a difference.

Christo Grozev is a Bulgarian investigative journalist who has spent years tracking down Russian spies and is on Vladimir Putin’s wanted list.

Grozev’s open-source journalism exposed spies linked to the poisoning of Sergei and Yulia Skripal in 2018 and Alexei Navalny in 2020.

Now he is at the centre of his own sinister Kremlin plot, as a Bulgarian spy-ring was sent by Moscow to target him and planned to kidnap and kill him, before they were arrested and convicted in the UK.

He speaks to Krishnan Guru-Murthy in this episode of Ways to Change the World ahead of the streaming release of his new documentary ‘Kill List: Hunted by Putin’s Spies’ - which is available on Channel 4.
