The IMF says that if Britain votes to leave the European Union next week, it could stifle economic growth and weaken the ties that bind the eurozone.

The International Monetary Fund warned that the 19-nation single-currency bloc already faces growing doubts from within that could loosen its bonds, arising from tensions over the refugee crisis and from financial strains. It said a pro-Brexit vote on June 23 could exacerbate that trend.

The IMF has already warned several times of a  potentially negative impact of a Brexit for British economy.  Christine Lagarde, the IMF managing director also expressed shock and sadness over the murder of British member of parliament Jo Cox.
