The UK's state pension is the least generous of all the most advanced economies in the world, according to a new study by the Organisation of Economic Co-operation and Development (OECD)
Only South Africa - which isn't a member of the OECD - is less generous.
The report found that the average pensioner can expect to receive just 29% of what they earned at work.
The pension systems in Japan, Germany, France, Italy, the United States, Canada, the Netherlands and Ireland all pay out a higher proportion of working income.
However, once "voluntary" pensions or workplace occupational pensions - are taken into account, the UK model fares better in comparison. When these additional pensions are included, the average UK pensioner receives 62% of his or her working income. This is still lower than the OECD average of 69%.
"The OECD has confirmed what we have long suspected - the UK is bottom of the league for pension provision," said Frances O'Grady, the TUC's general secretary."Working people in Britain face the biggest retirement cliff edge of any developed nation."
