An MOT is valid for a year because that is the law. A parliament is over a fixed period too. A referendum is final. Get over it.If you believe there is a majority for leave, then you must want a 2nd referendum to back that up.
After all youve just said, an MOT is only valid for a year and things change.
Anyway, there will be a 2nd referendum of sorts on December 12th. Will you accept the result of that one? I will.
