Only met Mrs D once...and for those brief few minutes found her all at the same time, charming, sharp, insightful and fully aware of what was going on around her (whilst being very carefully shepherded by some senior types). Also remember seeing on TV she and her Select Committee taking a couple of senior CAA people to pieces very efficiently - as ever asking straight questions and demanding similar answers.
As has been said by others, she had an integrity that is sorely lacking in our current crop of politicians (whatever their political persuasions) and her passing is a loss that I suspect will only be more fully realised as time goes by.
Loved to see her on Question Time too.
RIP.....but, if I'm wrong and there is something after we shuffle off, I have a feeling that Gwyneth will be making sure that it's working properly.
