Today, I'm joined by documentary photographer John Angerson, described as one of Britain's most creative and versatile photographers, on a walk along an ancient wall in Silchester, England. This wall, part of a once-thriving Roman town, nearly led Silchester to become England's capital.

We talk about his long-term project, Love Power Sacrifice, where for 20 years, John photographed a cult-like religious organisation called the Jesus Army. Also, how the most normal of scenes can be the site of the most extraordinary photo stories and how John gained the most incredible access to one of NASA's space shuttle flights.

It being the first Friday in the month, former guest John Dolan will be setting a new one-word assignment for June and there is news about our Photowalk adventure to Delhi, the Taj Mahal and Jodhpur in 2025.

Links to all guests and features will be on the showpage, my sincere thanks to MPB.com who sponsor this show and the Extra Milers without whom we wouldn't be walking each week.
