Britain leaving the EU could have a "negative and substantial effect" on the UK's economic growth, the International Monetary Fund has said.
"A vote for exit would precipitate a protracted period of heightened uncertainty, leading to financial market volatility and a hit to output," the IMF said in a report published on Friday.
IMF chief Christine Lagarde has defended the organisation's "negative" assessment for UK growth in the event of a Brexit, amid varying forecasts for its outcome, particularly in the long-term.
Speaking to Julie Etchingham, she said: "It's difficult to predict 50 years ahead for sure, but you can certainly determine in the short-term, the consequences of uncertainty."
When questioned as to whether over the longer-term, there is no conclusive answer on whether it would be good or bad for economy, Lagarde said:
Asked why people should listen to the IMF, when they have admitted they have got things wrong in the past, Lagarde said: "Like everybody else, we sometimes are wrong in our assessment."
"This particular exercise was conducted over the course of many weeks by a really strong team. They listened to all the economists, they looked at all the numbers," Lagarde added.
