Fixed term bonds - Atom, Paragon and Sensible Savings

I have a friend in Nigeria who is able to get really good interest rates, into 2 digits guaranteed, with no upper limit.

Just send a cheque, made out to me, with the the amount you want to invest and I will forward it on to him

Also consider Corporate Bonds: higher interest rates, true, but with a degree of risk.

You have to choose one or the other; you can't have both!
