The Minister may, after consultation with any Board, give to that Board directions of a general character as to the exercise and performance by the Board of their functions in relation to matters which appear to him to affect the national interest.

A Board, in framing and carrying out proposals involving substantial outlay on capital account by the Board or by a subsidiary of the Board, shall act on lines settled from time to time with the approval of the Minister.

In the exercise and performance of their functions as to training, education and research, each Board shall act on lines settled as aforesaid.

Without prejudice to the foregoing provisions of this section, the Minister may, after consultation with any Board, direct the Board to discontinue any of their activities, dispose of any part of their undertaking, dispose of any assets held by them, call in any loan made by them or exercise any power they may possess to revoke any guarantees given by them:

Provided that the Minister shall not give any such directions unless he is satisfied that the carrying on of the activities or the retention of the part of the undertaking or the assets or the continuance of the loan or guarantee, as the case may be, is unnecessary for the proper discharge of the duties of the Board under this Act.

The Minister may, after consultation with any Board, direct the Board to exercise their control over a subsidiary of the Board so as to require the subsidiary to discontinue any of their activities, dispose of any part of their undertaking, dispose of any assets held by them, call in any loan made by them or exercise any power they may possess to revoke any guarantees given by them.

If it appears to the Minister that there is anything which a Board ought in the interests of national defence to have power to do, or which a Board ought in the interests of national defence to be required to do, and that it would be consistent with the duties imposed on that Board by this Act, he may authorise or direct the Board to do that thing; and no limitation on the powers of the Board contained in this Act or in any local enactment shall prevent the Board from acting in accordance with the authorisation or direction.

Each Board shall furnish the Minister with such returns, accounts and other information with respect to their property and activities, and the property and activities of any company which is their subsidiary, as he may from time to time require.

Without prejudice to the provisions of the last foregoing subsection, each Board shall, as soon as possible after the end of each accounting year of the Board, make to the Minister a report on the exercise and performance by them of their functions during that year and on their policy and programme, and the Minister shall lay a copy of every such report before each House of Parliament.

The report for any year shall set out any direction given by the Minister under this Act to the Board during that year, unless the Minister has notified to the Board his opinion that it is against the interests of national security to do so, and shall include a statement of the salaries or fees and of the emoluments of each of the members of the Board during that year.
