I want to know the answer to the following question:
Which papers did Morgan serve as editor of?
All the background I'm provided with is that "Television personality Piers Morgan, a former editor of the Daily Mirror and of The Sun's Bizarre pop column, has said that during the late 1980s, at Kelvin MacKenzie's behest, he was ordered to speculate on the sexuality of male pop stars for a feature headlined "The Poofs of Pop".". Is that enough to answer the question?
