4The Greater London development plan shall be treated for the purposes of this Act as a structure plan for Greater London approved under section 4 of this Act and may be altered under section 5 of this Act accordingly ; and the Minister may direct that any area or part of an area indicated by the plan (as originally approved under section 5 of the principal Act) as an area intended for comprehensive development, redevelopment or improvement as a whole shall be treated for those purposes as an action area.
5The structure plan required by section 2 of this Act to be prepared for any area by a London borough council shall include a restatement of so much of the provisions of the Greater London development plan, with any alterations and additions consistent with the latter plan which appear to them to be necessary or expedient, as is applicable to that area.
6A London borough council shall send any report and structure plan prepared by them under the said section 2 to the Greater London Council for submission to the Minister, and the Greater London Council shall send them on to the Minister within such period as he may allow, with any observations of theirs thereon.
7The information on which a London borough council's policy and general proposals formulated under section 2(3) of this Act are based shall include any information which the council obtain in pursuance of a direction of the Greater London Council.
8The inclusion in the Greater London development plan of an area wholly or partly within a London borough which is to be treated as an action area shall not preclude a London borough council from selecting any other part of the borough as an action area.
9Before giving a direction to a London borough council under section 2(4) of this Act the Minister shall consult the Greater London Council and the London borough council with respect to the proposed direction.
