The cost of living rose by 9% in April, said the ONS. Earlier this year, anti-poverty campaigner Jack Monroe criticised large supermarkets for “stealthily” removing value food ranges from their shelves, forcing shoppers to “level up” to higher priced goods.
She criticised the way the way that the rate of inflation was calculated – which measures a wide range of goods – stating that it “grossly” underestimates “the true cost of living crisis”.
