As I read it, and pardon me if I do not understand - I am sure the Minister of State is struggling as well - under section 166, which is the "Effect of expiration of duration of permission":

Subject to subsection (3), a permission granted under this Part shall, on the expiration of its duration, cease to have effect as regards— (a) the entire development, where the development to which the permission relates is not commenced prior to the expiration of the duration of the permission, or

(b) so much of the development as is not completed within the duration of the permission, where the development to which the permission relates is commenced within that duration.

What we are dealing with says that shall not apply "in relation to retention permission for any unauthorised structure".
