Gary Lineker: My Grandad’s War
9pm, BBC One
Gary Lineker’s grandfather Stanley Abbs didn’t talk about his wartime experiences. On this trip to Italy, the footballer-turned-TV presenter gets an inkling as to why. Abbs was a member of the Royal Army Medical Corps and must have seen terrible things. Lineker’s pride is obvious as he meets veterans, gets a crash course in battlefield medicine and explores the nickname “D-Day Dodgers”, which was sometimes disparagingly applied to soldiers in the Italian campaign.
