The Prime Minister said:

“Independent studies show
that a vote to leave would hit the value of the pound, making imports
more expensive and raising prices in the shops.”

it ever joined the EU.

“If you’re going to ever expand the EU,
you have to allow us to mitigate the security risk that comes with

meant it wouldn’t become a member until the year 3000.
