Top easy access cash isa (if you need it) is 3.0% easy access or 4.25% fixed for a year. Both with Virgin Money but need to apply for current account Chase current account still offers 1% Cashback on all debit card spending and 1% interest. Also best rates if using abroad. Alternatively earn £175 Cashback if you switch to First Direct current account Amex Cashback platinum card for credit

A fools game. Contrast that with the return I am getting from my investment in the "Nigerian Guaranteed High Growth Tax-Free Investment Fund" through my broker Charles Windsor Churchill of Royal Mayfair Wealth Advisors. 25% return each month per the emailed statements, all of which is being reinvested commission free !
