The view of the Supreme Court of the United Kingdom was that the &quot;interview&quot; was, in practical terms, equivalent to arrest under English and Welsh law. From memory (though this was years ago!) a formal charge must be occur at the end of an interview. There&#x27;s no distinction, in the view of the Supreme Court, between the interview and the arrest.<p>The argument that he&#x27;s only wanted for interview was a large part of his defence prior to entering the embassy, and was entirely shot down by the courts.
