I would be interested to know exactly what you think Ms. Harmon needs to apologise for, and to whom that apology should be directed at?
It was appropriate,particularly with hindsight, for Pat Hewitt to apologise, being the Gen Secretary of the NCCL at the time of PIEs affiliation. It was possibly appropriate for Shami Chakrabarti to apologise, being the Gen. Secretary of Liberty, the organisation which the NCCL became, for similar reasons - as the titular head of the organisations, the buck stops with them.
But Ms. Harmon was appointed after PIEs affiliation; Her work did not involve scrutiny of affiliated organisations - she was the NCCLs legal officer, offering opinion on policy positions.
I think Dromey and other senior executive members, might have more of a case to apologise, rather than Harmon. Dromey himself talks about defeating PIEs odious agenda within NCCL, so why, if their agenda was recognised as being repellant did the NCCL continue to take affiliation money? Why not expel them?
But you might just as well ask for the then Home Secretarys of the day to apologise for not outlawing the organisation. There is even a hint or suggestion that PIE got some kind of government grant money, although that is merely speculation at the moment.
The DM, in the manner of its framing of the headlines and the story, has sought to insinuate that Ms. Harmon was pro-paedophilia or assisted PIE in their paedophilia agenda, which reads to me like a smear campaign - not too dissimilar to the attempted smear on Ed Miliband when labelling his father, Ralph, as a traitor to the country.
