Dutch Finance Minister Jeroen Dijsselbloem has accused British Foreign Secretary Boris Johnson of giving Britons an unachievable vision of the U.K.'s future outside the European Union.

Dijsselbloem told the BBC that Johnson "is offering to the British people options that are really not available."

Johnson has been touring European Union capitals as Britain prepares to start exit negotiations with the 28-nation bloc.

He was quoted by a Czech newspaper as saying the U.K. would likely have to leave the EU customs union, but could retain access to the bloc's single market in goods and services.

Dijsselbloem said Johnson "is saying things that are intellectually impossible, politically unavailable."

On Tuesday the British government strongly rejected a report by a consultant for Deloitte claiming it had no coherent plan for Brexit.
