- Import and export systems, within businesses and at ports
- For functions currently being carried out by the EU that the UK government will be taking over. Some 20 new bodies, plus expnsion of those such as for Data Protection
- In businesses and other organisations to cater for any other adjustments
Any deal with the EU won't be till late 2018 or early 2019. So for no other reason there needs to be at least another two years for systems to be developed.
It simply isn't pragmatic to expect to exit the EU cleanly by March 2019. Nor is it sensible to just walk out of the talks with no deal. The systems will take another couple of years before they are all effective. The absence of working systems would make life extremely difficult, potentially catastrophic.
So to those clamouring for Philip Hammond to be sacked for seeking a transition, just think a moment about the practicalities. Thankfully there is at least one adult in the Cabinet.
I would go a stage further. I'm not a fan of the EU. But let's Stop Brexit and avoid all this nonsense. Put all those efforts into moving forward, not just trying to stay still.
