asked the Secretary of State for the Environment if he will introduce legislation to apply planning control to intensive livestock and horticultural buildings in areas of outstanding natural beauty.

The erection of farm buildings is within the limits specified in class VI of the General Development Order "permitted development" under that class. I have published proposals to remove class VI rights from new livestock buildings near housing, so that planning applications would be required; and proposals to qualify class VI rights in respect of farm and forestry roads and buildings in the national parks.
