I'd be very surprised if the public were asked if they wanted a no deal exit.
That's one of the suggestions going around - again probably to appease the Faragistas & the ERGonites who've changed their tune from 'rich Norway' (Farage), "no one's talking about leaving the Single Market' (Hannan?) and general cakeism (BoJo and all the rest of them) to anything other than a "clean break" is a "betrayal of Brexit means Brexit'.
I can understand that people are fed up of it dominating the news (aren't we all?), so the idea of a "clean break" (let's just get on with it, we survived the War after all) may appeal to some of those weary of the while thing.
However, the imminent reality of a "clean Brexit" is the equivalent of suggesting that everyone jumps of a cliff and hopes that parachutes will somehow appear out of nowhere. Or, if Grayling is in charge of ordering them, faulty umbrellas from a company that has never made any.
The idea that an isolated UK would then somehow be in a position of strength to dictate its terms is pure fantasy. It doesn't even happen in nature, let alone international negotiations.
