Morrisons trials 30p plastic bag charge

Its reusable plastic bags currently cost 20p, but the trial means that Morrisons' bags are now 20p more expensive than those in some other major supermarkets.

It's the third time the store has trialled increasing costs this year, with reusable bags having cost 10p in January.

The chain is also trialling increasing the cost of its paper carrier bags from 20p to 25p and says the money made from the scheme will be invested into "plastic reduction initiatives".

Morrisons says it won't give more details of the trial, including whether or when it will be expanded to more stores, but it's possible a national roll-out could follow.
