as for no risk. im not sure that exists. any bank can collapse and their exposure is limited to around �30-40,000 i think. though you'd have to ask the bank.

for a 2 year commitment UNITED TRUST BANK are offering 6.75% by the looks of things.
but if your cleverer you'll be able to beat that by quite a bit id have thought. try offshore accounts
