BRUSSELS, Oct 13 (Reuters)-France 's EU affairs minister on Tuesday called for cooperation in the 27-nation bloc over fisheries negotiations with Britain that are part of fraught wider talks aimed at keeping trade moving openly amid Brexit.

Clement Beaune, who came to Brexit for talks with EU partners before a bloc leaders' meeting later this week, said it " note that the 27 of them, the European Union, require a very unified strategy..."

He said that the bloc had to be "very firm" on top priorities including fisheries and fair competition safeguards, and said that the conditions for accessing the 450 million people without trade obstacles on the EU's internal market had to be "sine qua non."
