EU Antitrust Chief Talks Tough with Google

The European Union’s antitrust chief said that he might yet take a tougher stance toward Google in a long-running case that he and the company have been in talks to settle for more than a year. The announcement, by Joaquín Almunia, is a potential blow for Google, which reached a tentative deal with Mr. Almunia in February by agreeing to display rivals’ links more prominently in its search results.
