Older people's charity, Age Cymru, has warned almost 50,000 pensioners in Wales live in 'severe' poverty.
Graeme Francis, from Age Cymru, said: "All older people should have an adequate standard of living.
"No-one should be faced with a calamitous reduction in their standard of living when they retire or be resigned to a life where they are forced to choose between basic essentials in order to make ends meet."
The charity says more needs to be done to help support older people in Wales.
