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.
The prime minister has said the International Monetary Fund's Christine Lagarde "is the latest top economist" to issue a warning over the dangers of Britain leaving the European Union.
David Cameron said: "The IMF's Christine Lagarde is the latest top economist to warn leaving the EU could result in a recession - that would hit jobs and wages."
Speaking at the Treasury, the head of the IMF warned that a so-called 'Brexit' could be "pretty bad, to very, very bad" for the UK.
She also cautioned that leaving the EU would result in a "protracted period of heightened uncertainty" for the country and could see interest rates "rise sharply".
