In the final episode of the series we speak with Kay Jebelli, Competition & Regulatory Counsel to the Computer & Communications Industry Association in Brussels, to discuss how the UK Competition and Markets Authority (CMA) uses its powers to address concerns with so-called “killer acquisitions”, in particular in the technology sector.

Big tech is a hot topic in the antitrust world, not least for the CMA, which has set up its own digital markets unit, its only sector-specialist division.

With big tech, the wide-reaching nature of the CMA’s share of supply test and merger intelligence function – which we have discussed in previous episodes - come into their own and allow the authority to intervene in tech mergers around the world because of their potential effects on the UK market. Kay, a veteran of such cases on the side of the tech companies, discusses with Chloe Cumber the CMA’s approach, and how merging parties have reacted.
