The Cayman Islands opposition party has warned that passage of the International Tax Co-operation (Economic Substance) Bill, now before the Legislative Assembly, will result in significant population growth, as the financial industry will be forced to bring in large numbers of white-collar professional workers on work permits to fulfill the local management and control functions required by the new law. Opposition financial services spokesperson, Chris Saunders, said the Cayman Islands needs to be ready for a population of 100,000 if the Bill is passed and questioned its worth; given that some companies will inevitably leave the jurisdiction and further demands from international organizations will follow.
