Who gave those powers to the Secretary of State? Is the hon. Gentleman aware that this practically means that he has power to prohibit British subjects going abroad if he wishes? From where does he derive those powers?
I think we need some further explanation. Is this not giving power to some officials in the hon. Gentleman's office to prohibit people from travelling on their lawful occasions? Is it not out of the question to talk of the Royal prerogative? It is a matter for Parliament, surely.
