The UK government is expected to reject proposals to introduce a new salt and sugar tax in England when it announces its food strategy next week.

Monday’s policy paper comes after a review recommended taxing salt and sugar used in processed foods, restaurants and catering.

Boris Johnson previously called the proposal “unattractive” but a government source stressed its strategy would promote healthier diets.

Labour said it “failed to deliver”.

The government-commissioned independent review of the food system last year recommended the tax to incentivise manufacturers to reduce salt and sugar in food to improve people’s health.
