"detained for four days"

It was much longer than that.

Now The Immigration Minister has released some of the 'Secret Squirel info' - but unfortunately, for his credibility, that info was made public ages ago...

Commentors have said that The Immigration Minister's action in revoking the visa is very much like the 1933 behaviour of the 'government' in Germany - The Minister claiming that his actions were independent of the 'parallel process' of the Court.
