You might be onto something PS. All the stones point to Labour being in turmoil and more intent on fighting itself than acting as a coherent opposition for now and for the foreseeable future, so if the Tories want to rid themselves of this bumbling, narcissistic idiot then what better way than to give him the keys to No. 10 (and the nukes) and let him ruin himself...
Of course as we've just found out, these grand Tory plans to deal with internal discord through such proxy manners have a habit in backfiring.
