It seems only right doesn't it?
We are about to embark on the most important two years of negotiations in our lives, this CANNOT be undertaken by a Prime Minister who has not been elected by the public.
I think a petition calling for a GE would be better than one calling for a second referendum. We need to hear each candidate's plans for what they plan to get out of a Brexit deal and let us vote.
(And if one candidate plans not to invoke article 50, then let them tell us that, and let the country decide).
