The EU has unveiled a raft of measures to protect its vital interests in the event of a no-deal Brexit.
The European Commission on Wednesday recommended 14 measures in a number of area including financial services, air transport, customs and climate policy.
Among the plans are emergencies policies to avoid avoid full interruption of air traffic between the EU and the UK in the event of no deal.
He told reporters in Brussels that the contingencies cannot replicate the benefits of the EU withdrawal agreement and certainly cannot replicate the benefits of EU membership.
The measures unveiled by the Commission are all short-term and it says they should in principle not go beyond the end of 2019.
A no-deal Brexit will happen if Theresa May is unable to get her Brexit deal through parliament, and then decides to go ahead with Brexit anyway.
