Maybe that is what Labour need.
They might take a lesson from Cameron getting into power by disguising himself as a 'one nation' Tory but once there, opened his neo-liberal box of nasty tricks.
So it could be argued that Labour need a similar Trojan horse to get into power and suddenly reveal their agenda when they get there.
It probably couldn't because pious lefties are so intent on preaching the gospel rather than getting things done.
Damn those lefties with their values and open intentions.
