No, I don't. Nobody does. Do you? There are plenty of quotes on Brexit, use Google. Do you know how much much Brexit has cost the UK economy? If you are so concerned about quotes, then provide them...
And the greatest cost to the economy, is from uncertainty....
Anecdotal I admit, but employment is up, the economy is doing well, house prices haven't collapsed...unfortunately!!!
As for World War Three... still looking unlikely.
I'm trying to think if Mr Lazy or Mr Wrong would be a more suitable moniker.
