Tesco is pulling a bunch of products because Unilever are trying to pull a fast one and trying to do some dodgy price gouges blaming it on Brexit and Tesco (led by a former director of Unilever who knows that business quite well) didn't fall for it so entered a confrontation.

Good for Tesco's. The idea that a fall in sterling means Unilever needs to put the price of Marmite up 10% when 100% of the world's Marmite production occurs in the UK is absurd. Nice try Unilever now fuck off, thankfully I hate Marmite anyway. Got enough Colman's English Mustard to get me through this confrontation.
