True, but May has (repeatedly) threatened to go out 'without a deal' if she can't get terms she likes.
The UK has to somehow bluff its way into a negotiation position and I fail to see how all these statements and laws are compatible with each other.
> the UK will be able to revoke its notification of article 50 but this must be “subject to conditions set by all EU27 so they cannot be used as a procedural device or abused in an attempt to improve the actual terms of the United Kingdom’s membership”. [1]
So in short, remaining is less likely than ever but still possible.
