(1)Where the Mayor has published the transport strategy as revised but it appears to the Mayor that a London borough council has failed—
(a)to prepare such revisions to the council’s local implementation plan, or
(b)to submit to him for approval such a local implementation plan as proposed to be revised,
as the Mayor considers necessary in order to implement in the council’s area the transport strategy as revised, the Mayor may issue to the council a direction under section 153 below requiring the council to do so within such period as the Mayor shall specify in the direction.

(4)Where the Mayor—
(a)refuses to approve under subsection (2) of section 146 above a local implementation plan as proposed to be revised, and
(b)has served on the London borough council who submitted the plan a notice under subsection (3) above,
the Mayor may prepare a revised local implementation plan on behalf of the council.
(5)In preparing a revised local implementation plan the Mayor shall consult the bodies and persons required to be consulted under subsection (5) of section 147 above, taking the references in paragraphs (a) and (e) of that subsection and in subsection (8) of that section to a local implementation plan prepared on behalf of a London borough council as references to a revised local implementation plan prepared on behalf of such a council.
(6)A revised local implementation plan prepared by the Mayor under this section shall include the matters specified in section 145(1) and (3) above.
