Which FCA conduct rule requires acting with integrity?

• A. Act with integrity
• B. Act with due skill, care and diligence
• C. Must observe proper standards of market conduct
• D. Must be open and cooperative with the FCA and PRA

Answer: (A)

Acting with integrity is the explicit obligation in the FCA conduct rules. It requires honesty, fairness, and trustworthiness in all professional dealings, meaning you don’t mislead clients, you disclose conflicts of interest, and you uphold ethical standards even when it’s inconvenient. This rule is the foundation for how professionals should behave in regulated firms, and it directly answers the question because it literally tells you to act with integrity. The other rules cover related but different expectations—being diligent, being open with regulators, and observing market standards—but they don’t state the core directive to act with integrity.
