 The UK arm of Spanish banking group Banco Santander has been fined 107.79mln by the Financial Conduct Authority FCA after the regulator found serious and persistent gaps in the banks anti-money laundering AML controls, affecting its business banking customers. Over a period of almost five years, from end-2012 to mid-October 2017, Santander UK failed to properly oversee and manage its AML systems, which significantly impacted the account oversight of more than 560,000 business customers, the FCA said in a statement.
