As many of you will be aware, 31st October 2019 is now the date in which the UK is due to leave the EU.
Assuming that we do leave at that date, and in a "no deal" scenario, the relevant schemas that are accessible at the following link, will come into place:
In addition, a further Brexit schema is required - this will be a replacement AA01 (to allow a minor enumeration change). I hope to be able to release this soon.
I would again reiterate that these changes will only come into effect if no deal is agreed between the UK and the EU.
