If upon representations made to him by any local education authority the Minister is satisfied that by reason of difficulties arising out of war conditions or out of conditions occasioned by the coming into operation of Part II of this Act temporary accommodation for children who are, or whose parents desire them to be, registered pupils at any voluntary school is required until permanent accommodation can be provided for them by the managers or governors of the school in accordance with the development plan for the area, the Minister may authorise the local education authority to provide, or assist in providing, such temporary accommodation in accordance with arrangements approved by him, so, however, that any such authorisation shall be withdrawn as soon as there has, in the opinion of the Minister, been sufficient opportunity for permanent accommodation for such pupils to be provided by the managers or governors of the school.
