Following the publication by the Financial Action Task Force’s statements identifying jurisdictions with strategic deficiencies in their anti-money laundering and counter-terrorist financing regimes
HM Treasury has now published an advisory notice for firms to:

• consider certain jurisdictions (listed in the advisory notice) as de facto high risk for the purposes of the Money Laundering Regulations 2007. Firms should apply enhanced due diligence
  measures in respect of these jurisdictions in accordance with the risks; and
• take appropriate actions with regard to these listed jurisdictions in order to reduce associated risks. This may include enhanced due diligence measures in high risk situations.

A copy of the advisory notice is available.
