The European Commission will next month issue a new complaint against Google, as well as freshening one of its two existing cases.

EU competition chief Margrethe Vestager is set to issue two statement of objections against the company for abusing its market power, according to sources. One covers online advertising and the second relates to online shopping.

The story was first reported by Politico.

The EU charges on online advertising are new and relate to Adwords, so making them potentially a bigger concern for the search giant than the other two lines of enquiry it faces.

The complaint on online shopping is longstanding. The new charge represents a supplement to the existing objections made by the commission. The additional arguments could be used by the commission to strengthen their existing case.

The other case being pursued by the EU at present relates to Android, where the commission has found Google guilty of unfairly using its market power to  impose unfair restrictions on device manufacturers and operators.
