How can anyone vote for something that has no definition? But they did.
No, they voted for it based on lies, fake promises (that are being destroyed on a near-daily basis. See kelvin’s Twitter link above) and misinformation.
How can a government implement something that has no definition? But they will.
Even they don’t know what they’re implementing! They are genuinely making stuff up to fit their ideas on a daily basis, contradicting themselves and saying what they think people want to hear. Every time they are pushed on what the final outcome will be they go all vague and quiet. Brexit is now happening but we as the general public have no idea what shape it will finally take as those in charge have no idea.
