Ford's European arm has hit out at government subsidies to rival car firms, saying they are leaving it at a competitive disadvantage.
Speaking in response to Germany's 1.5 billion Euro (£1.3bn) government-backed bridge financing for General Motors' Opel arm, and the French government's 6.8 billion Euro (£6bn) loans to PSA Peugeot Citroën and Renault, Ford's European boss John Fleming said he was "very concerned".
Fleming has urged the European Union to "maintain proper oversight" of the growing number of national and pan-European aid plans for the car industry.
While Ford is not reported to be opposed to aid packages for car makers, it wants the funds to be made available to all car makers on equal terms. In the US, for instance, Ford has been offered loan assistance from the government in the same way as GM and Chrysler, but has chosen not to draw on it.
"Given this background of an apparent current lack of enforcement of EU state aid and internal market rules, it is imperative that any bridging loans that might be provided by the German government for Opel do not breach EU state aid or competition policy," Fleming told the Financial Times newspaper.
