Judging by the comments below he let Jacqui Smith off the hook (surprise) over Damian Green. According to PoliticsHome’s transcript when “asked about claims Mr Green had been bugged she said she would have had to sign a warrant for that to happen and she had not”. More when it is up on iPlayer.
UPDATE 11.50 : According to comments below the PoliticsHome transcript is incorrect. Pretty crucial detail to get wrong if they have.
UPDATE 12.20 : Have now watched the interview. She gave the impression, but did not state that she had not authorised bugging. Marr actually seemed better than average.
