The Secretary of State may—
in relation to a proposed national policy statement, extend the period mentioned in section 5(4A), or
in relation to a proposed amendment of a national policy statement, extend the period mentioned in section 6(7A),
by 21 sitting days or less.
The Secretary of State does that by laying before the House of Commons a statement—
indicating that the period is to be extended, and
setting out the length of the extension.
The statement under subsection (2) must be laid before the period would have expired without the extension.
The Secretary of State must publish the statement under subsection (2) in a way the Secretary of State thinks appropriate.
The period may be extended more than once.
