Extraordinary Portraits

BBC One, 8.30pm; Ni/scot/ Wales , 11.10pm

A Shetland cancer survivor and lifelong knitting fanatic, the indefatigable Harriet Middleton is heroically attempting to fundraise a six-figure sum to equip the islands’ small hospital with an MRI scanner. Figurative portraitist Stuart Pearson Wright is wrangled by Tinie to visit the islands in order to capture her likeness for the first episode in a new run of this gently affecting, highly creative series.
