BRUSSELS--The European Union has extended Google Inc.'s deadline until Aug. 31 to respond to charges that the U.S. company is skewing its search results to favor its own comparison-shopping service, a Google spokesman and the European Commission both said Thursday.

The Commission, the bloc's antitrust regulator, had set a deadline for Aug. 17 after previously granting Google additional time so it could review the documents that allege that the company favors its comparison shopping function in search results.

The EU filed the formal complaint in April, when it also opened a separate probe into its Android mobile-operating system.

Commission spokesman Ricardo Cardoso said Google had requested the additional time to respond to the charges in the shopping search case.

"The Commission analyzed the reasons for the request [and] as a result, it has granted an extension allowing Google to fully exercise its rights of defense," Mr. Cardoso said.

It wasn't immediately clear why the company asked for the second extension.

The Commission frequently grants extensions in major antitrust cases, to ensure that companies are given ample opportunity to defend themselves. That helps avoid legal hurdles if the regulator needs to defend its judgment before the EU's appeal courts in Luxembourg.

Google earlier this week announced it would restructure its company, separating its highly profitable search and advertising business from its other ventures and organizing them under the holding company Alphabet Inc.

The EU in response had said those changes wouldn't affect its antitrust investigations into the company and that it was sticking to its latest deadline for Google to respond to the formal charges in the shopping search case.

The EU's charges, the first formal complaint against Google by an antitrust regulator, could lead to billions of euros in fines and requirements for the company to change its business practices.

The formal complaint could also be broadened to include other domains, such as travel and local services, where Google is accused of favoring its own services over those of others.
