Martin Lewis has called on people with cash ISA bank accounts to "ditch" them, as he claims they have no benefit for many people.
A cash ISA is a type of savings account that lets you earn interest on your savings without paying tax on it, though you can only pay £20,000 into it each year.
The main advantage of cash ISAs is the ability to receive interest without paying income tax, but they are also good for people who need easy access to their funds.
