The brief answer is that in our annual plan we set out our measure of outcomes: benefits for people in terms of great choices and fair deals; benefits for businesses in terms of enabling them to compete, innovate and thrive; and benefits for the economy as a whole in terms of growing productively and sustainably. That applies across the new suite of roles, powers and responsibilities. If you are looking at outcomes for people, what is the impact on prices and choice? Can people access their data? Can they move between services more effectively? What is the impact on businesses? Can they get fair and reasonable terms when they are reliant on the infrastructure of some of these major players in order to innovate and grow? Are we seeing innovation coming from smaller businesses as well as the incumbents? When we look at the benefit for the economy as a whole, do we see the flow-through of greater competition, improving productivity and improving growth? We have our “State of UK competition” report, which reports on that, and that will continue to be an important metric.

We are taking on responsibility for an annual consumer protection study, again looking at areas of consumer concern and the impact of interventions we are taking. You mentioned international benchmarks; I think that is really important. Obviously, a lot of these issues, especially on the digital side, are international in nature. We want to see benefits in terms of changes in international trends—there is a real opportunity here for the UK to set the model for positive regulatory intervention in digital markets, and for that to be adopted by others—and real benefits for UK businesses in terms of their ability to grow and innovate, and the investment that that attracts from overseas.
