Clarkson's Farm breakout star Harriet Cowan makes emotional plea

Clarkson's Farm breakout star Harriet Cowan has made an emotional plea as she fronted a new farming campaign. The glam farmhand, 24, stole the show in series four as she arrived on screens to assist at Diddly Squat Farm while Jeremy Clarkson's usual helper, Kaleb Cooper , was away. But after leaving the show, Harriet has returned to her family farm and shared a powerful message to the public and the government this week about the 'dying industry', asking them to 'put British farming on the map'.
