A Very British Cult

Journalist Catrin Nye shares the results of her 18-month-long investigation into a mysterious life coach who took over clients’ lives.

The Repair Shop
8pm, BBC One
A family oil painting, a glass terrarium and a clay footprint are this week’s challenges for the restoration experts.

This week, in a documentary series where the running theme is heroic professionalism in the face of dwindling resources: surgery is needed to investigate a growth on a patient’s lung: such procedures are always at the risk of last-minute cancellation.
