§ Mr. Bercow
To ask the Prime Minister what regulations or conventions exist to provide for the maintenance of political neutrality by European Commissioners in speeches targeted at a national audience in an area of domestic controversy. 
§ The Prime Minister
Commissioners must act in accordance with the Community Treaties. They are required by Article 157 of the Treaty establishing the European Community to be completely independent in the performance of their duties. As such, they are not allowed to take instructions from any Government or from any other body, and must refrain from any action incompatible with their duties.
