Google should be broken up if it won't stick to EU competition rules, say European Parliament lawmakersÂ Google is accused of biasing its search results in favour of own services European Commission has already spent four years investigating the firm Tech lobbyists call unbundling anÂ 'extreme and unworkable' solution By Damien Gayle for MailOnline and Reuters and Associated Press Google should be broken up if it won't stick to European Union competition rules, members of the European Parliament said today. European Union lawmakers overwhelmingly backed a motion urging antitrust regulators to get tough on Google and other Internet search engines over allegations of biased search results. The resolution was passed with 384 votes for versus 174 against and is the strongest public signal of Europe's concern with the growing power of U.S. tech giants. The Google headquarters in Mountain View, California: European Union parliamentarians say the online search and advertising company should be broken up if it won't apply EU competition rules 'Clear adoption by EP of digital single market motion, including unbundling for search engine if needed,' Spanish liberal lawmaker and co-sponsor of the bill, Ramon Tremosa said on Twitter. Google is the target of a four-year investigation by the European Commission, triggered by complaints from Microsoft, Expedia, European publishers and others that it promotes its services at their expense. The resolution did not mention Google or any specific search engine, though Google is by far the dominant provider of such services in Europe with an estimated 90 percent market share. The lawmakers called on the Commission, in charge of enforcing fair competition in the European Union, to consider proposals with the aim of unbundling search engines from other commercial services. The European Parliament in Brussels:Â The resolution was passed with 384 votes for versus 174 against and is the strongest public signal of Europe's concern with the growing power of U.S. tech giants While the legislature has no power in the matter, the call to the Commission is intended to increase pressure on new antitrust chief Margrethe Vestager to act quickly. Technology lobbying group Computer & Communications Industry Association, whose members include Google, eBay Facebook, Microsoft and Samsung, said unbundling was an 'extreme and unworkable' solution. While clearly targeting Google, the parliament is in fact suggesting all search companies, or online companies with a search facility, may need to be separated. This is of great concern as we try to create a digital single market,' it said.
