For those who would prefere a second referendum, should push for a hault of this BREXIT process, mentioning the obvious uncertainty, whether the public still hast he same understanding about the BREXIT consequences.
It is important to do this, because legislation to do so is needed first: So lay the ground for this proposal and if this is agreed, an orderly argumentated proposal attempt to proceed for another referendum should work through. This should be decorated by the wish to remain for a longer time within the EU. Rather for more than two years.
However, you should rush to do so, because the EU has to prepare itselfe, to accept a propably complex consensus.
