Morrisons is donating £10 million worth of produce to help restock the nation's food banks.
Chief executive David Potts said its bakery, egg, and fruit and vegetable departments will run for an extra hour every day to make, prepare and pack food required to restock the services.
It will also be sending deliveries of ambient food - such as canned goods and pasta - to local food banks via "community champions".
Potts said: "As a food maker and shopkeeper we are uniquely placed to help.
"We know food banks are finding life very difficult and running our manufacturing sites for an extra hour each day to help restock them is the right decision at this time.
"The core purpose of all 96,537 colleagues at Morrisons is to play our full part in feeding the nation."
The retailer, which typically serves more than 12 million customers every week, said it also wanted to encourage customers to make donations by lifting purchase limits to four items and removing limits on some items altogether.
Morrisons isn't the only major player to take action to try and get essentials to food banks.
Co-op has announced it will be donating £1.5 million worth of food to FareShare, the UK’s largest hunger fighting charity, and B&M said it would make each of its 650 stores donate £1,500 of essentials to their nearest food banks too.
Co-op Food chief executive Jo Whitfield said: “Food banks have never been more important, so it makes sense that we provide support to help FareShare keep people fed and watered during this unprecedented time."
She added: I would ask everybody if they can, to contribute to a food bank near to them. Every tin, jar or carton makes a difference”
B&M chief executive Simon Arora said: “Many of the communities we serve have households in them that are really struggling to buy their groceries due to recent lay-offs.
"We hope that this donation at grass roots local level across the whole of the UK will allow some essential groceries to get to those who need them as quickly as possible.”
