Who was it?

Duncan Garner has tweeted:

I won’t out my original source Hooton. They’re still leaking despite ‘all being behind’ Shearer.

and also:

I’m not going to get into this, except to say my source is within the caucus.

So if it was MP. The question is, which one. We can’t know for sure, but logically one would expect it to be an MP who:

1. Was not a supporter of Shearer in the ballot vs Cunliffe
2. Has been demoted by Shearer since then
3. Was a supporter of the “man ban”
4. Has little to lose by leaking as they are likely to retire at the next election, or prior to that

One can’t blame Chris Carter for this one.
