Conditions For a Halton By-Election?

I think Garth is now saying that if the PM promises to call a by-election right away, Turner will step down right away.

I say "I think" because I'm still not certain whether Garth is still insiting that at the very least, a by-election be called for W. Khan's riding as well. It depends what quote you read.

I've said it before: Garth should step down, without conditions, because he has made the whole issue of changing horses in mid-stream such a big deal.

But if Garth's not insisting on Khan, or anyone else, resigning before Garth agrees to live up to his own principles, then that's a much more interesting situation - and it puts the ball right back into the PM's court.

More later.
