This week Sarah looks at how ISAs work. What are the different types available now, and how do they all work? Are they still the best option for savers? Figures published last week showed that 12.7m people had an ISA in the tax year up to April, down slightly from 13m last year. With savings rates so low, maybe that's not surprising.
