(1) Subsection (2) applies if the CMA considers that it is under a duty to make a reference under section 22(1) or 33(1) (disregarding the operation of section 22(3)(b) or (as the case may be) 33(3)(b) but taking account of the power of the CMA under section 22(2) or (as the case may be) 33(2) to decide not to make such a reference).

(2) The CMA may, instead of making such a reference and for the purpose of remedying, mitigating or preventing the substantial lessening of competition concerned or any adverse effect which has or may have resulted from it or may be expected to result from it, accept from such of the parties concerned as it considers appropriate undertakings to take such action as it considers appropriate.

(3) In proceeding under subsection (2), the CMA shall, in particular, have regard to the need to achieve as comprehensive a solution as is reasonable and practicable to the substantial lessening of competition and any adverse effects resulting from it.
