3Without prejudice to his powers under section 4 of this Act, if at any time during the year 1974-75 it appears to the Secretary of State that, but for the provisions of paragraph 2 above, he would have made an, order under section 3 of the 1966 Act increasing the amount fixed by the rate support grant order for the year 1973-74 as the aggregate amount of the rate support grants for that year, he may by an order made in lice manner and subject to the like provisions as a rate support grant order—
(a)increase the amount fixed by the rate support grant order for the year 1974-75 as the estimated aggregate amount of the rate support grants for that year by an amount equal to the increase for which he would have made provision in the order under section 3 of the 1966 Act; and
(b)make such increases in all or any of the elements of rate support grants for that year as appear to him to be appropriate in consequence of the increase in the estimated aggregate amount of those grants made by virtue of sub-paragraph (a) above.
