EU set to announce Google action
The EU is expected to set out later the action it will take against Google over alleged anti-competitive behaviour.
Margrethe Vestager, the competition commissioner, could make a statement about her intentions on Wednesday.
Reports suggest she will announce that a "statement of objections" is being prepared.
Such action would mark an escalation in the Commission's handling of complaints that Google favours its own products in search engine results.
Google accounts for more than a 90% share of EU-based web searches.
The company has yet to respond.
The European Commission has investigated the antitrust allegations - made by Microsoft, Tripadvisor, Streetmap and others - since 2010.
They object to the fact that the firm places reviews from Google+, directions from Google Maps, music and videos from YouTube, and adverts from its Adwords platform ahead of others' links in relevant searches.
"At the core must be the fundamental principle that Google must not abuse its power in general online search to give preferential treatment to its own separate services," Icomp, a lobbying group representing the complainants, said earlier this year..
This involves sending a letter that sets out all the objections the commission can base its final decision on, and is a legal requirement, providing Google an opportunity to respond before action is taken.
Such action would mark an escalation in the Commission’s handling of complaints that Google favours its own products in search engine results.
“If Google takes the view that users are best served by search results that integrate additional services, Google must choose the services that benefits consumers most, even if the services are not its own“.
“Google is a gatekeeper to different markets, and I think they will want to make an example of it,“ said Paul Henty, a lawyer at Charles Russell Speechlys who has previously worked for the European Commission.
They object to the fact that the firm places reviews from Google+, directions from Google Maps, music and videos from YouTube, and adverts from its Adwords platform ahead of others’ links in relevant searches.
However, the US Federal Trade Commission dropped its own probe at the start of 2013 after Google made several non-binding commitments.
Last year, Google agreed to alter the way it displayed its search results, but the changes it suggested were deemed to be insufficient.
