The political situation in Cuba is unsettled at present, principally due to the inability of the Grau administration to solve shortages in meat, milk and other essentials.
Internal dissension within Grau ranks has been evidenced by the open enmity of his revolutionary adherents for his so-called "Palace Clique" which is led by Chief of Police Jose Carreno (Fiallo), Sub-Secretary of Defense.
