The solution is simple. The Leave movement argued that we needed to leave the EU so that we could 'bring back control', and to ensure the British Parliament was wholly sovereign again. So let's just do that. Let's let Parliament vote now on the final implications/options of the advisory referendum result. Options currently on the table are: 'no-deal', 'May's deal', 'Stay' (sounds so much nicer than 'remain'). Doing exactly what Leave asked for. Who on earth could complain about that?
