I have spent the last few weeks thinking there was a "No Deal Brexit" legislation, after reading in the parliament library it shows that the vote on 13 March 2019 is not legally binding. So when people say Number 10 is working towards a no deal Brexit, it might still be possible.
How can a no deal Brexit happen?
Article 50 of the Treaty on European Union provides for an EU Member State to leave the EU with or without a withdrawal agreement or ‘deal’.
No deal could be the result of various scenarios:-
The EU and UK do not agree on the terms of a withdrawal agreement and/or a framework for future relations because of lack of time and/or because there are intractable disagreements and no willingness to compromise, the talks break down.
There is agreement in principle on the substance of a withdrawal agreement but more time is needed and the other EU Member States refuse to extend negotiations.
There is agreement in principle on the substance of a withdrawal agreement but more time is needed for certain details.
The UK Parliament rejects the negotiated withdrawal agreement and framework for future relations in the vote under Section 13 of the EU Withdrawal Act.
The European Parliament rejects the negotiated withdrawal agreement and framework for future relations.
The Council does not endorse the withdrawal agreement by an enhanced qualified majority (20 of the 27 Member States, representing 65% of the EU population).
A withdrawal agreement is concluded and enters into force, but at the end of the implementation/transition period there is no agreement on future EU-UK relations; or there is an agreement, but it has not been implemented in the UK because the bill to implement it has not been passed, or it has not been ratified in the EU Member States and has not entered into force provisionally.
