The maker of Marmite and other popular food and household products has warned that some price rises are inevitable.
Unilever has said it expects its own input costs to rise by up to £3 billion this year and will have to pass some of those increases on to the consumer, according to the Mirror.
The firm is behind Ben & Jerry's and Magnum ice cream and Hellmann's mayonnaise and also owns well-known brands such as Dove, Domestos bleach and Vaseline.
