Can the Brexit process be stopped and restarted again?
Reality Check
The Attorney General and Conservative MP Ken Clarke have disagreed about whether Article 50 (the process which started the UK's two-year departure from the UK) could be cancelled - in order to give MPs more time to reach a consensus - and restarted later.
Geoffrey Cox told Mr Clarke that Article 50 could not be revoked unless "satisfactory evidence" was given to the EU to show the UK was ending the Brexit process altogether, rather than just pausing it.
So is Geoffrey Cox right?
It's true that the European Court of Justice (ECJ) has granted the UK the power to independently stop the Brexit process. But its ruling also says that "revocation brings the withdrawal procedure to an end".
So if the UK tried to revoke Article 50 just to buy more time, the EU could argue such a move does not comply with the ECJ's ruling.
But if the EU rejected a revocation request on that basis it's unclear how it would enforce it, according to Joe Owen from the Institute for Government.
