In the first episode of the new series, with his simpering secretary Alex Horne in tow, Taskmaster Greg Davies beckons a fresh quintet of quivering comics into his world of misrule: Fatiha El-Ghorri, Jason Mantzoukas, Mathew Baynton, Rosie Ramsey and Stevie Martin. Their success in this series opener will rest on their skills in tasks involving vinegar, raisins and, as is traditional, peas.
