The U.K. should expect a fight in its negotiations to secure a Brexit from the European Union, the President of the Eurogroup, Jeroen Dijsselbloem, told CNBC.
European and Asia markets were shaken up on Friday, after sterling briefly dived 6 percent, with traders struggling to find out whether it was a "fat finger error" or related to fears over Brexit.
While no official reason has yet been given for the pound's sharp fall, one suggestion is linked to comments made by French President Francois Hollande, who said that the EU had to remain firm with the U.K..
Dijsselbloem said the reactions seen across the continent in recent days were more related to some "quite stern comments (which) were given, sounding like a hard Brexit" during the Conservative Party conference in Birmingham by Prime Minister Theresa May and her cabinet on subjects including immigration and the jurisdiction of the European Court of Justice.
"I think the effects of Brexit have yet to sort of trickle down. We really are still in the process of trying to understand it," said Dijsselbloem, telling CNBC that "we need a good deal. We need it sooner rather than later, however complex it may be."
