I’m a promoter of democracy. I voted to Remain. Now that the consequences of Brexit are clearer (by no means chrystal clear) I consider it would be democratic to hold a referendum based on accepting May’s Deal v Remaining within the EU. Not to hold such a referendum would be wholly un-democratic.
Assuming we voted to Remain, I would have no problem with a further referendum in say 10 years time based on a reconsidered proposal to Leave. This time the politicians would have to have a proposal well laid out and a clear indication that is was acceptable to the EU as well, unless the proposal was clearly “A No-Deal Brexit”
