UK financial service regulators have launched an investigation into Equifax over its handling of the recent mega-breach.

In a brief statement on Tuesday, the Financial Conduct Authority (FCA), which could fine the firm or revoke its right to operate in the UK, said it was "investigating the circumstances surrounding a cybersecurity incident that led to the loss of UK customer data held by Equifax Ltd on the servers of its US parent".
