Eric LawtonI get that politicians may have to change their mind when circumstances change.
So I propose a law that they have to demonstrate to an open, independent tribunal that the change made a material difference to their logic.
Failure to do so would lead to a fine or resignation, depending on the seriousness.
As it is, flip-flops have a major impact on our faith in politicians and representative democracy in general
