EU Said to Ask Google’s Foes to Share Evidence in Probe

Google Inc.’s antitrust foes were asked to allow the search-engine giant to see secret evidence they gave to European Union regulators, two people familiar with the case said.

The EU request for complainants to declassify some of their documents may be a sign that officials are preparing to escalate their four-year-long antitrust investigation, according to the people who asked not to be identified because details of the probe aren’t public.
