<p>Tom Weldon, chief executive of Penguin Random House UK, used his opening keynote at the London Book Fair on Tuesday to draw what he called a firm "red line" on an issue that has been quietly building tension in the rights community: the growing practice of European publishers acquiring English-language rights to books, which Weldon characterised as "a very, very dangerous situation" for the UK and US publishing industries. The remarks were prompted by the recent case of Bonnie Garmus — the author of the PRH Transworld bestseller Lessons in Chemistry — who signed her new book, Peck & Peck, with Bonnier, with a deal structure that gave Bonnier's German subsidiary Piper the rights to publish the book in both German and English across Europe. Weldon confirmed that PRH had declined to match the offer on principle.</p><p>"We didn't lose her," Weldon told Bookseller editor Philip Jones, who conducted the keynote interview. "We decided to lose her. And the reason is a very important principle for us, which is that we will not contract a book from any agent who sells English language rights to a European publisher." The rationale, Weldon explained, is structural rather than competitive. Because Europe operates as an open market, English-language books sold by European publishers can flow freely across the continent and into global online retail platforms — meaning that stock could end up in the UK and the United States at prices and on terms that UK and US publishers have not agreed to. "There is a potential race to the bottom on price," Weldon warned. "Unsold stock could end up anywhere in Europe through global online retail platforms. Books would end up in the UK and in America. It would be confusing for retailers. It will be confusing for consumers. This is an absolute nightmare."</p><p>The underlying dynamic Weldon is describing has been building for several years, driven by the increasing ambition of European publishing conglomerates — particularly the large German and Scandinavian houses — to compete for global English-language bestsellers rather than simply acquiring translation rights. For these publishers, acquiring English-language rights to a major title offers a route to direct participation in the world's largest book market without the overhead of maintaining a full UK or US publishing operation. For UK and US publishers, the practice represents a potential erosion of the territorial rights framework that has underpinned the economics of English-language publishing for decades.</p><p>Weldon was careful to frame PRH's position as protective of the broader ecosystem rather than merely self-interested. "We don't do that because we're throwing our weight around. And we don't do that because we're intransigent. We do that to protect the much broader book ecosystem for everybody." The argument is that the territorial rights system — which allows publishers to invest in authors, build audiences, and price books appropriately for specific markets — depends on the integrity of those territorial boundaries. Once English-language rights begin flowing to publishers who operate primarily in a different market, the pricing discipline and distribution control that make those investments viable begins to erode. The Garmus case, from Weldon's perspective, is a test of whether the industry will hold that line or allow it to be gradually dissolved by individual deal economics.</p><p>The London Book Fair has historically been the moment when rights deals are made and market norms are negotiated. Weldon's public statement of PRH's position — delivered from the opening keynote stage rather than in private conversations — is a deliberate attempt to establish a precedent that other major publishers might follow. Whether they do will depend in part on whether the agents and authors who are attracted by European publishers' offers conclude that the long-term ecosystem argument outweighs the short-term deal advantage. That calculation is unlikely to be resolved quickly, but Weldon has ensured that the terms of the debate are now clearly on the record.</p>
