Leighton is on summer break, so we are highlighting some of his favourite guests from 2022.

"One of the most damaging statements of a world leader was from Jacinda Ardern, that there will only be a single source of truth. We need to rediscover the virtues that brought about the effloresces of scientific discoveries which have made the world infinitely wealthier, healthier, better educated and better fed."

So says Emeritus Professor Ramesh Thakur. Outstanding commentary from a great thinker.
