International credit-debt watcher Fitch Ratings sounded the alarm bells over dark clouds looming over the horizon of British bookmakers Ladbrokes Coral and William Hill.

Fitch warned that the United Kingdom may likely to impose tougher-than-expected betting restrictions on in-store gaming machines in the next few months, following the completion of its triennial review.

 “The UK government is likely to propose changes to the regulation of gaming machines in the next few months, following the completion of its triennial review,” Fitch analysts Paula Murphy and Patrick Duncan said in a note issued on Wednesday. “Our base case is for an incremental tightening of regulations that would mainly affect smaller, independent companies with less diversified revenue streams. But we have also considered an adverse scenario where gaming machine revenues are significantly affected.”

When this happens, Fitch pointed out that Ladbrokes and Hill are the most likely to get affected by the changes made by the UK government.
