Take, say, Hugo Swire. He has not said how he would vote. Say Mrs May wins – he can say he voted for her but could have voted against her as the ballot is secret.
Or, if she loses he can say he voted against her to be in with a chance with a new Leader.
Although Parish says he voted for her, he can’t prove that either – he might have secretly voted against her!
Doesn’t matter what those declared and undeclared voters voted for – it can never be proved.
Transparent? Of course not!
