The European Union has announced that it has been investigating the terms of Google's proposed deal to partner with Yahoo for advertising.
The deal would see Google's advertising programmes built into Yahoo's search engine in the US and Canada.
However, the EU Competition Commission argues that there are anti-trust implications because the two companies do business in Europe.
The EU's present inquiry could escalate to a formal investigation.
