I want to know the answer to the following question:
What was the accusation leveled by Ronald Spark against The Daily Mirror, The Guardian, and BBC?
All the background I'm provided with is that "After HMS Sheffield was wrecked by an Argentinian attack, The Sun was heavily criticised and even mocked for its coverage of the war in The Daily Mirror and The Guardian, and the wider media queried the veracity of official information and worried about the number of casualties, The Sun gave its response.". Is that enough to answer the question?
Answer: no
