I think worst case scenarios have already been factored into the markets. No deal we go to world trade tariffs its not a disaster. Listening to radio5 a motion to cancel brexit altogether could happen. Worse case is a state of limbo where we cant trade with anybody which could happen with current deal offered by Eu?
I say not. The reason being the market hates uncertainty the most,and after the vote there will be greater clarity as to which direction we are heading in?
