There are only two things that former ministers – the big beasts of a party – can be in relation to an incumbent leader: silent or unhelpful. To offer advice in public is to imply that private counsel has not been sought or not been heeded. No veteran politician thinks his experience is worthless or irrelevant so the very act of commenting in public contains a rebuke to the younger generation, which is why no amount of code and caveat prevents it being reported as such.
So it was with Tony Blair’s comments in the centenary edition of the New Statesman, Peter Mandelson and Alan Milburn in the Independent, David Blunkett in the Observer and John Reid all contributing to the discussion of what Ed Miliband should be doing. Not silent, therefore not helpful. That isn’t a comment on their collective insight or entitlement to an opinion it is just a fact of the way news reporting works.
