6As respects the County of London—
(a)the Minister may by order determine the extent to which grants to voluntary associations in respect of maternity and child welfare services carried on by them are to be apportioned as if they had been grants to the London County Council, on the one hand, and to the common council and the metropolitan borough councils on the other hand;
(b)the loss on account of grants of the common council or of a metropolitan borough council shall be the loss on account of grants of the council as a spending authority, together with the loss of such part, if any, of the grants to voluntary associations as may be apportioned to the council under the last foregoing paragraph and the appropriate proportion of the loss on account of grants of the receiver for the metropolitan police district.
