I want to know the answer to the following question:
Complaints to which body led to The Sun removing the story from its website?
All the background I'm provided with is that "The UK magazine Private Eye claimed that Glen Jenvey, a man quoted by The Sun as a terrorism expert, who had been posting to the forum under the pseudonym "Abuislam", was the only forum member promoting a hate campaign while other members promoted peaceful advocacy, such as writing 'polite letters'.". Is that enough to answer the question?
