The UK’s anti-organised crime agency says it is awaiting decisions on whether suspects will be charged after investigations into serious sanctions breaches.

The National Crime Agency (NCA), which investigates the most serious and deliberate breaches of sanctions, including flouting the oil price cap, warned that investigations are lengthy, and similar bribery cases take about seven years in industrialised countries.

Only a small proportion of its work involves investigating sanctions breaches and just one Russian has been charged with criminal offences since the invasion of Ukraine.
