As I understand it a "yes" vote would effectively be "throwing a six" for the serious discussions to start.
Presumably, ahead of the next General Election, all the mainstream parties would then have to adopt a position in the light of that vote (not necessarily the same as the position they might take ahead of a vote).
The more I think about this, if my only interest was an academic, historical one, it would be really fascinating.
Some of the private client brokers have started issuing generic notes to their clients/the world at large trying to outline what some of the issues would be and matters to be considered around the FS industry. The numbers of people/Analysts/Project Managers that would need to be employed to work it all out would be massive (thinking just about Banking, Insurance and Investment).
