Part 1: Digital Markets Procedure Section 11: Procedure relating to SMS investigations
This section sets out how the CMA should carry out an SMS investigation. Under section 118, an SMS investigation means an initial SMS investigation and a further SMS investigation. This section therefore applies to both types of SMS investigation.
	Subsection (1) requires the CMA, when beginning an investigation, to give an SMS investigation notice to the undertaking subject to the investigation.
	Subsection (2) sets out what the SMS investigation notice must cover.
	Subsection (3) sets out what the statement of the purpose and scope of the investigation must include. The investigation may relate to more than one digital activity.
	Subsection (4) requires the CMA to give the undertaking a revised version of the SMS investigation notice if it changes its view of the purpose and scope of the investigation.
	Subsection (5) sets out that as soon as reasonably practicable after giving an SMS investigation notice, or a revised version of the notice, the CMA must publish the notice and give a copy of the notice to the Financial Conduct Authority, the Office of Communications, the Information Commissioner, the Bank of England and the Prudential Regulation Authority.
