Good morning. Our Mobile Sector Assessment is a chance to take stock of the role of regulation in a sector that affects almost every UK consumer, at home and at work. Our starting point is our two principal duties, to promote the interests of citizens and of consumers, including by promoting competition. These duties are at the heart of our analysis. This morning, I’d like to: briefly explain what the Assessment seeks to do, in the context of Ofcom’s wider strategic approach to telecoms talk about what we see, when we look at the sector today focus on the question of termination rates, which raise particular challenges for industry and regulators. The MSA - general The purpose of the MSA is to identify whether and how regulation needs to adapt to a changing market. Our goal is to ensure that the sector contributes fully to the UK economy and society.
