Mr. Joe Durkan:

Investment will fall because of the uncertainty - people will not know what to expect of the market. This is not just speculation as it happened in the 1970s at the time of the last referendum. Investment did actually fall and that inevitably reduces a country's long-run potential growth. There will be uncertainty if the UK does leave as to what the terms of any trade agreements will be. Everyone will call for them to remain more or less as they are because otherwise it is very disruptive. If UK income falls it will impact on Europe because it means Europe will sell less. It is important we do not see weakness in an economy as an advantage because it really is a disadvantage. The richer countries become the better it is for everybody because they are then more likely to be able to trade successfully.
