My right hon. and learned Friend is right to talk about the need to avoid cliff edges. To that extent, I can agree that today we are seeking to create a situation whereby we will have the flexibility to leave if ratification takes place. That aspect of his intervention is a very important one to remember. The negotiability of the position is simply that the talks between the parties are ongoing and if there is something fruitful as a result, we can proceed to use the provisions of section 13, with which all of us are notably very familiar. Those stages can then be passed and ratification will be deemed to be complete.
