IMF says Britain leaving the EU is a significant risk
Christine Lagarde, the head of the International Monetary Fund, has warned that if Britain was to leave the European Union the impact would range from "pretty bad to very, very bad".
She says leaving the European Union would hit British growth, investment and house prices.
Vote Leave campaigners say the IMF has been wrong before about the British economy and is wrong again.
