Seyi Rhodes investigates the impact of the government's latest benefit cap on some of the families affected by it. Ministers introduced the cap because, they said, they wanted to make sure that work paid more than benefits; they wanted it to force people to change their lifestyles, to live on less money or go back to work. Rhodes discovers that, while some people are now changing their lifestyles, the cap's unintended consequences may mean pushing the benefits bill up in other ways.
