The government is set to unveil a groundbreaking overhaul of merger scrutiny in Britain, with plans that could significantly impact the country's economic landscape. This week's announcement from the Department for Business and Trade (DBT) will introduce a series of reforms aimed at enhancing efficiency and transparency in the process of evaluating corporate mergers. The key changes include the abolition of the Competition and Markets Authority's (CMA) panels system, a move that will reshape the way mergers are assessed for antitrust concerns. The government source suggests that the CMA's jurisdiction may be limited, particularly for mergers involving foreign entities, and the ability to appeal against merger decisions may be curtailed while retaining the option for judicial reviews. The CMA's market investigations will be streamlined, merging into a single, more efficient process lasting between six and 12 months. This reform is seen as a significant step towards faster decision-making and increased business certainty. The CMA will also establish a sub-committee to scrutinize more detailed Phase-2 investigations and another to oversee broader market studies, with the CMA's CEO, Sarah Cardell, potentially serving on these committees, thereby increasing her influence over the cases under investigation. However, concerns have been raised about the potential for political influence and the independence of merger investigations, sparking debates on the balance between regulatory efficiency and political discretion.
