|Tom Watson and Jeremy Corbyn|
I find myself guessing the personality types of the new Labour leadership. New leader Jeremy Corbyn is a classic INTP (which makes him similar to me). Profiles present him as rather solitary, not a team player, courteous to a fault, non-confrontational, not interested in the small stuff and infinitely stubborn over matters dear to his heart. Such people are rarely natural leaders.
His deputy, Tom Watson, seems to me an ESTJ (not sure how extravert). This is in line both with his reputation as a fixer/operator and with his claimed loyalty to the party. There are irresistible comparisons to the pairing of Blair (ENTP) and Prescott (ESTJ): the thinker and the enforcer.
The Machiavellian component (INTJ Peter Mandelson, anyone?) is surely provided by the third principal, the new shadow chancellor John McDonnell. Since I had never heard of him, for the moment the jury is out, though.
The unions will come to regret backing Corbyn; Andy Burnham would have been far more biddable.
