If she wishes to roll over for the DM, then, let her do it.
I can't see any evidence that Patricia Hewitt is 'rolling over' for the Daily Mail. The NCCL/Liberty has in the past issued an apology and admitted its mistakes for its past links with PIE, this has nothing to do with the Daily Mail. It's quite appropriate that the former general secretary of the NCCL should restate those points at the present moment, with all the media coverage the issue is receiving.
It would in fact be quite ridiculous for those concerned to pretend that was nothing wrong with the NCCL accepting PIE under its umbrella.
