“If a statement of an immigration policy was flexible and stated that an immigration rule relating to leave to enter and remain in the United Kingdom might, depending on the circumstances of each case, be relaxed if certain conditions were satisfied, the statement itself was not an immigration rule and therefore the Secretary of State was not required to lay it before Parliament in accordance with section 3(2) of the Immigration Act 1971.”
