The International Monetary Fund (IMF) Managing Director Christine Lagarde said on Friday that a British exit (Brexit) from the European Union (EU) could weigh on the Britain's outlook.
"Uncertainty associated with the outcome of the planned referendum on EU membership could weigh on the outlook," she said.
"Certainty is always better than uncertainty," the IMF managing director added.
Lagarde said that she hoped the country would stay in the EU.
