If you go buy a box of chocolates you don't just buy the pretty box- hopefully there are chocolates inside. Same with exit from the EU. Since first joining a lot of EU legislation has been put in place.
How much of that needs review and/or repeal, modification is anybodies guess.
The whole procedure has been reduced to farce because the Tories were so confident the remain vote would win that the implications and procedures that would follow an exit vote obviously were not even considered.
As many have already stated in british law there is no provision for a legally binding referendum. For this to occur Parliament would have to become subordinate. As I understand it even with our unwritten constitution, Parliament cannot abrogate it's responsibilities to enact legislation.
What the Tories have managed to create is potentially a constitutional nightmare. By giving the people a referendum and then not confirming that vote in Parliament seriously questions their legitimacy. Forcing through a vote with a majority at this time is an unlikely scenario. Interesting times!
