From next year, the small print in bank documents may not be smaller than a whopping two milimetres high - this to help us from being, ahem, misled.

The new rules, supported by the Banco de España, contain the rider that 'entities providing credit must act honestly, impartially and professionally, based on the personal and financial situation and preferences and objectives of their clients. They should also highlight any condition or characteristic of the contract which does not meet this objective'.
