Sales: £256.6m (-10.8%)

With not-from-concentrate juice the second worst performing sector in juice and shoppers giving canned goods the cold shoulder, Princes’ £31m decline is the fifth steepest of the year. A ‘robust’ promotion plan combining on and off-shelf activity for juices and lowering the average price of tuna by 8.7%/kilo is how the brand plans to fight back. But it’s not all about price. It’s innovated with a Thai chilli tuna salad and limited-edition Moroccan, Mexican and Indian mackerel flavours.
