Fiat has decided not to attend talks in Berlin with the German government which will decide the chosen bidder for General Motors’ European division.

The Italian carmaker said the German government was “unreasonable” in its expectations for extra funding to buy the business. However, Fiat still maintains that it is interested in buying GM Europe, .

A decision on who would be the preferred bidder for GM Europe was expected on Wednesday but this has now been delayed as parent company GM has now asked for more cash for the European division.

The four bidders vying for the company are Fiat, Canadian car parts maker Magna, Brussels-based investment firm RHJ International and the Beijing Automotive Industry Corporation.
