Santander falls 5% in the stock market after accusations that Iran used bank accounts to avoid sanctions. Santander spokesperson assured Europa Press: "We cannot comment on clients.

Santander complies with its legal and regulatory obligations, and we pay close attention to regulatory compliance with sanctions imposed on third parties." For their part, Lloyds shares have accumulated a fall of 1.3% in these first hours of trading. The revelations about the Iranian sanctions evasion operation in London come after the Royal Air Force recently joined US airstrikes against Iran-backed Houthi rebels in Yemen.
