Borders, Citizenship and Immigration Bill [HL]

My Lords, in answering that question from the noble Lord, Lord Hylton, is the Minister saying that the discretion in the Bill is unfettered but that guidance will be given that, while not legally binding, will somehow be taken into account? Is that the position? If the discretion is unfettered, that seems inappropriate. If the Minister is saying that there will be guidance that will, in some way, limit and define the discretion, that position is much more acceptable. I am not clear what he is saying on that.
