The Secretary of State may, after consultation with persons appearing to him to represent the interests of landlords and tenants of agricultural holdings, by order vary the provisions of Schedules 5 and 6 to this Act.

An order under this section may make such provision as to the operation of this Act in relation to tenancies current when the order takes effect as appears to the Secretary of State to be just having regard to the variation of the said Schedules effected by the order.

Nothing in any order made under this section shall affect the right of a tenant to claim, in respect of an improvement made or begun before the date on which such order comes into force, any compensation to which, but for the making of the order, he would have been entitled.

Orders under this section shall be made by statutory instrument which shall be of no effect unless approved by resolution of each House of Parliament.
