Anslinger notified the Cubans that the US would block all shipment of narcotic prescription drugs while Luciano was there.

The day before the wedding, King George VI bestowed the style of Royal Highness on Philip and, on the morning of the wedding, 20 November 1947, he was made the Duke of Edinburgh, Earl of Merioneth, and Baron Greenwich of Greenwich in the County of London.
