From today's Telegragh, this time quoting Hewitt "defending" Harman and Dromey:
Miss Harman, who joined NCCL as its legal officer in 1978, has insisted that PIE had been marginalised by the NCCL in 1976, when it “took them on and pushed them to the margins”. Her husband Jack Dromey, an NCCL executive committee member from 1970 to 1979 and now a Labour MP, has said he took on PIE and helped drive them out.
Miss Hewitt defended the couple, saying: "When Jack Dromey, as NCCL chairman in 1976, vigorously opposed PIE at the NCCL AGM, he did so with the full support of the executive committee and myself as general secretary.
"Harriet did not join the NCCL staff until 1978. She was one of two legal officers, neither of whom was a member of the executive committee."
I'm still not seeing the straightforward "guilt" on HH's part that some other posters are seeing.
