Unilever has vowed not to work with any firm from 2030 which does not pay staff a living wage.

The consumer goods giant, which makes ice cream at a factory in Gloucester, said it was working with supply chain partners to establish rates of pay across 190 countries.

And it said it would pay staff twice as much as the minimum wage in some countries.

A company statement said: "Our ambition is to improve living standards for low-paid workers worldwide.

"We will therefore ensure that everyone who directly provides goods and services to Unilever earns at least a living wage or income, by 2030.

"We will work with our suppliers, other businesses, governments and NGOs - through purchasing practices, collaboration and advocacy - to create systemic change and global adoption of living wage practices."

The Anglo-Dutch firm, which includes Marmite, Dove soap, PG Tips, Persil and Domestos among its products, has more than 60,000 direct supplier globally.
