Sarah Cardell:

My view is that it is entirely the opposite. Competition and open competitive markets are the foundation of an economy that encourages investment, innovation and growth. We see that from a vast range of economic literature and economic research. The work that the CMA already does is very much tied to driving innovation, investment and growth.

So the starting point is that open competitive markets are good for innovation, good for investor confidence and good for growth. We then need to make sure that the design of the regime delivers that, and that the implementation of the regime, by the CMA, delivers that. I think the design does, for the reasons that I broadly outlined, and obviously the scrutiny is then, rightly, on the CMA to make sure that in practice we deliver the regime in a way that inspires that confidence.

I think we will do that in a number of ways. The first is to look at the outcomes that we deliver, which will ensure that businesses, large and small, are able to grow, invest and thrive in these markets. The second way is to make sure that we have really strong stakeholder engagement. This is not a regime where we want to operate behind closed doors. The whole design of the regime is a participative approach where we will engage with a broad range of stakeholders, businesses and consumers as we consult on designation, design the conduct requirements, and then enforce against them.
