In the year 2000 there were barely any food banks in the UK but today there are nearly three thousand. So what's behind the sharp rise and how did it get to a point where the government says we have "a mass dependence" on food banks?

In this episode Jaega Wise tells the story of the food bank. She hears from those using the Bristol North West food bank. They talk openly about how the food bank helped turn their lives around. She also visits a "social supermarket" in south London where people on benefits are able to shop from donated stock cheaply.

Dr Andy Williams from Cardiff University discusses how the food bank model was imported from the United States where it had its roots in the Great Depression and Emma Revie of the Trussell Trust gives her view on why there has been such a surge in food bank usage.

Jaega also visits Middlesbrough where the former Prime Minister Gordon Brown is opening a "Multibank" - these are warehouses full of donated stock that includes food and other household goods. Gordon Brown talks about his ambition to open Multibanks all over the country to tackle the growing problem of food insecurity.
