Google faces a record-breaking fine for monopoly abuse within weeks, as officials in Brussels put the finishing touches to a seven-year investigation of company’s dominant search engine.

It is understood that the European Commission is aiming to hit Google with a fine in the region of €3bn, a figure that would easily surpass its toughest anti-trust punishment to date, a €1.1bn fine levied on the microchip giant Intel.

Sources close to the situation said officials aimed to make an announcement before the summer break and could make their move as early as next month, although cautioned that Google’s bill for crushing competition online had not been finalised.

The maximum possible is around €6.6bn, or a tenth of Google’s total annual sales.

It will mark a watershed moment in Silicon Valley’s competition battle with Brussels. Google has already been formally charged with unlawfully promoting its own price comparison service in general search results while simultaneously relegating those of smaller rivals, denying them traffic.

The stakes have been further raised by a new investigation into alleged monopoly abuse related to Google’s Android smartphone software.
