Dutch Prime Minister Mark Rutte is questioning British optimism that departing the European Union will lead to a brighter future, saying the United Kingdom could be in for "potentially irreparable harm."

In unusually frank terms toward a longstanding allied nation, Rutte says British growth has remained good since last year's Brexit vote only because the pound has sunk so low. He adds that "if you look below the surface, the English economy suffers potentially irreparable harm because of their Brexit."

Rutte says the Brexit vote has already led to a "tectonic shift" within the international banking community that still has London as one of its biggest global hubs.
