In May 2016, Mark Carney, said: “we would expect a “material slowing in growth, a notable rise in inflation, a challenging trade-off” in the case of a Brexit vote. He added, “of course there’s a range of possible scenarios around those directions, which could possibly include a technical recession”.
In the same month, the Treasury said: “Britain’s economy would be tipped into a year-long recession, with at least 500,000 jobs lost and GDP around 3.6% lower, following a vote to leave the EU, new Treasury analysis launched today by the Prime Minister and Chancellor shows.”
Didn't happen did it.
