Expert is defined as a person whose research, knowledge and experience accords them the respect of their peers in a well-distinguished domain.

Those who take the former position point to a saving for the Exchequer of some £8bn each year; a return to sovereign integrity and the restoration of democratic self-determination in all areas of national life.
