STATE REFINERY: The ministerial economic committee which met yesterday chaired by Prime Minister Constantine Karamanlis discussed the operation of the state oil refinery and decided to recommend the following solution to the Cabinet: to announce a new competition to be decided on December 20 to lease the refinery. Interested parties will have to be clear and bids must benefit the state in some way. Otherwise the government will suggest that the state itself operates the refinery, contracting out only the technical management. The committee reached its decision after weighing the advantages and disadvantages of all possible solutions.
