UK unable to prove case for sanctions against Russian oligarchs like Abramovich, Times says

Britain will not be able to sanction Roman Abramovich and other Russian oligarchs for weeks or months because the government has been unable to prove reasonable grounds for designating the businessmen, The Times newspaper reported.

"The Foreign Office and National Crime Agency have been unable to prove that there are 'reasonable grounds' for designating the UK's most prominent oligarchs for sanctions because they have struggled to link their finances to the Putin regime," The Times said.
