A jar of Marmite is arranged for a photogaph in Brenchley, south east England, on October 13, 2016. British staple Marmite was taken off the virtual shelves at British supermarket Tesco on Thursday, following a reported row with supplier Unilever over pricing after the pound plummeted on fears over the UK's Brexit plans. Jars of Marmite were "currently not available" in the online store of Tesco -- the world's third biggest supermarket chain -- after the company reportedly refused Unilever's request to hike prices. / AFP / BEN STANSALL (Photo credit should read BEN STANSALL/AFP/Getty Images)
