Ten law firm partners have been identified as the top U.K. M&A lawyers based in London for 2025, according to a dataset produced by MergerLinks. Samuel Newhouse of Latham & Watkins topped the rankings, and was found to have led on M&A transactions last year with a combined deal value of £54.05 billion. Newhouse was part of the Latham team which advised on the merger of mining giants Anglo American and Teck—creating a $53 billion combined group. Notably, every lawyer on the MergerLinks list of the top ten practitioners is male. The online platform’s final list is based on the total value of M&A transactions announced last year, and considers only those in which the respective lawyers led teams in which their firm was the primary legal adviser. The list also features top names from Freshfields, Skadden Arps Slate Meagher & Flom, Cravath Swaine & Moore, A&O Shearman and Slaughter and May. Freshfields partner Stephen Hewes was in second place on the list, having led on deals with a combined value of £21.9 billion, while Skadden partner Denis Klimentchenko was in third place with an equivalent figure of £15.8 billion. Freshfields' Hewes advised on CVC's acquisition of Smiths Detection from Smiths Group for £2 billion in December 2025, with Latham & Watkins also leading on the deal.
