REPUBLIKA.CO.ID, BERLIN -- The European Union's digital economy commissioner said on Monday Britain should act quickly to implement its departure from the European Union to limit uncertainty that is rattling investors.

"The next step must come from London," Guenther Oettinger, EU Commissioner for Digital Economy and Society, told the Deutschlandfunk German radio station.

Oettinger said every day of uncertainty was preventing investors from putting their funds into Britain and other European markets.
