Very difficult question, Steve. If Parliament thinks no-deal is unacceptable it makes sense to leave it off the question paper. But without a shadow of doubt, that would cause massive anger amongst those who voted to leave. However, if it is on the ballot and people vote for remain - or even May's deal - I am not convinced their anger will be much less. Also, if Parliament has decisively rejected May's deal, it would be odd to put that as an option.

All the questions I can think of have problems but I find Soubry's idea of ranking May's deal, no-deal and remain in order the best.
