Chancellor George Osborne has warned United Kingdom residents that the nation would be “permanently poorer” if it leaves the European Union.
BBC reports that a Treasury analysis found that if the U.K. exits the E.U., its economy would be 6% smaller in 2030 than if it stays.
“The conclusions could not be clearer. Britain would be permanently poorer if we left the E.U. to the tune of £4,300 for every household in the country. That’s a fact everyone should think about,” Osborne said.
Detractors say that a prediction out as far as 2030 can be disputed, and that the Treasury hasn’t always made accurate forecasts in the past.
There’s a vote on E.U. membership scheduled for June 23.
