The British public did vote for brexit even though it was as plain as the nose on your face that it would be harmful to the economy.

"As plain as the nose on your face".
Pre the vote we were told that the pound would 'tank' that there would be an immediate 'black hole' in the economy of £60k, that unemployment would go through the roof.
None of these happened.
'Project fear" totally failed.

I, for one, don't believe that my voting for Brexit has been proved to be a failure. And I'm happy to say so.
Brexit was a necessary readjustment of our relationship with 'Europe'.

Whatever our current problems (exchange rate with the Dollar, inflation rate, unemployment rate) Europe (the EU bloc) have similar problems!
