A matter of national security

The United Kingdom government offers a number of savings products through National Savings, some of which offer tax benefits. There are also products such as bonds which pay interest gross, and they can benefit savers who do not pay tax, though they are not tax free and tax has to be paid by other savers. The Premium Bond is a way to save and gamble at the same time, since the bonds are put into a prize draw each month, and investors can seek the return of their stake money.
