John Connolly (a pro-Israeli blogger, rather than the horror writer) claims that he was leaked the Nawi details by a member of Higgins' campaign team, which is not to say that either Labour HQ or Higgins himself provided any info. For what it's worth, this has reached a whole new level to the first controversy, in that this was entirely Norris's own disaster, due to total naivety and an inexperienced backroom team, who should have been prepping him for every worst-case-scenario type issue. He should have the good sense to cut his losses and make a dignified exit, but it doesn't appear that that's how it will play out.
