Parliamentary Scrutiny of Leaving the EU

Is it not also incumbent on the Government to be mindful that article 50 was not put into the Lisbon treaty to make it less complicated to leave the European Union? If we try to include too many things under article 50 that stray into mixed competences, we will finish up with an agreement that requires unanimity? That would lead to a far more protracted negotiation than if we try to keep things simple. In fact, it would be an advantage to business if we could complete this in a much shorter period than the two years specified under the article 50 process.
