Will a sugar tax work? Well, it did at Jamie Oliver's Italian restaurants

Researchers say the chef's 10p levy on sugary drinks led to a significant drop in sales - boding well for the government's sugar tax plan

Jamie Oliver's 10p tax on sugary drinks sold in his Italian restaurants has resulted in a significant drop in sales, a study has found.

The Jamie's Italian chain introduced the sugary drinks tax to set an example as part of a campaign to persuade the government to take action. In June 2015, Oliver announced that every drink containing added sugar would cost 10p extra and that the money would help pay for food education and water fountains in schools.
