They are, but that is because Cameron and now May are trying to weasel out of the referendum result. If they were genuine they would have activated Article 50 the day after the referendum, which would have concentrated minds, provided a framework (and some certainty) and brought about meaningful negotiation.
Instead we have this absurdity, that is damaging the economy (probably deliberately) and bringing about confusion.
Couldn't agree more. IMO, the Tories are working out whether the greater loss is to 'renege of democracy' or to go off into such an uncertain horizon.
