not when the decision has been delegated to the people via a referendum. At that point MPs have forfeited their right to ‘do the right thing’ and must then accept what the people decide.
Stridently stayed though that might be, it is also codswallop.
With that line of argument you are going to, again, end up backing yourself into one of those corners that inevitably await anyone arguing for Brexit being allowed to go ahead.
And FWIW, I strongly believe that the economic cataclysm that anything but the softest of Brexits will cause will do infinitely more damage to our ‘democracy’ than ignoring an advisory referendum ‘won’ narrowly by a pack of lies. The political nutcases want a No Deal for precisely this reason. Stopping Brexit will do political damage, no doubt, but the long term agony that going ahead will cause will lead us to a much, much darker place, and these political exploiters know it.
