The resolution, which was approved by 384 votes to 174 (with 56 abstentions), focuses on the online search market and its "particular importance in ensuring competitive conditions within the digital single market." In other words, unbundling would safeguard against Google and other search engines favoring their own services in search results.
The parliament called on the European Commission to "consider proposals with the aim of unbundling search engines from other commercial services."
The non-legislative resolution is more of a suggestion to European Union regulators than an order for EU member states. The message, however, is clear: Parliament members want the European Commission to "prevent any abuse" that could arise from interlinked services by search engine operators.
Although the resolution impacts all search engines — not only Google — it comes after a four-year probe into the company's search and advertising practices.
The resolution also reinforces the European Parliament's support of net neutrality, stating that “all internet traffic should be treated equally, without discrimination, restriction or interference.”
Google did not immediately respond to a request for comment.
The move is aimed at reducing the search giant's search and advertising monopoly in the 28 member state bloc, amid concerns spanning more than three years over the company's business practices.
Draft documents seen by The Financial Times show the European People's Party (EPP) and the European Socialists & Democrats (S&D), the largest parties by seats in the European Parliament with more than half the votes, backing a motion that calls for the search giant to split up.
"Unbundling [of] search engines from other commercial services" could appease those concerned by Google's dominance in the European market, the publication cited the motion as saying.
The draft motion is the most far-reaching of all proposals to date.
Although the motion, if passed, would not force Google to split up, it would pressure the European Commission, which is accountable to the European Parliament, to seek resolution from Google.
Failing that, Google could be barred from operating certain services in the region.
The European Commission declined to comment.
Google, which has about 90 percent of the search market share in the European Union, has come under heavy fire from European parliamentarians and regulators alike for its alleged business practices.
Those allegations, detailed in a May 2012 letter to Google chairman Eric Schmidt, include copying content from competing search engines, and restricting the portability of data out of its advertising platform to competing services.
The leak of the draft motion comes less than two weeks after Europe's new antitrust and competition commissioner, Margrethe Vestager, said it would take time to consider the next step in the ongoing probe.
The probe as it stands is currently in hiatus as Vestager evaluates the European Commission's next move.
"The issues at stake in our investigations have a big potential impact on many players; they are multifaceted and complex. I will therefore need some time to decide on the next steps," Vestager told members of the European Parliament in a hearing in Brussels.
Despite three rounds of concessions, her predecessor Joaquin Almunia ultimately rejected the third and final offer, leaving Vestager to handle the Mountain View, Calif.-based technology giant.
Should Google be found in breach of Europe's antitrust or competition rules, it could be fined up to 10 percent of its global revenue for the infringing years.
A vote in the European Parliament is expected on Thursday, according to the FT.
