IMF warns of substantial Brexit risk to UK economy
A vote for the UK to leave the European Union could have a "negative and substantial effect" on economic growth, the International Monetary Fund said.
In its annual health check of the UK economy, the IMF said that a Brexit vote would result in a "protracted period of heightened uncertainty".
That would cause volatility on financial markets and economic output to decline.
Such concerns may have already affected UK markets in recent months, it added.
The IMF pointed to a 40% decline in the number of commercial real estate transactions in the first three months of the year.
It pointed out that the choice of whether to remain in the UK was a choice for voters to make and that "their decisions will reflect both economic and non-economic factors".
