What lead to the conspiracy theories that swirled in the aftermath of Diana’s death - and what role did BBC journalist Martin Bashir play in the final years of Diana’s life? In the final of our seven-part series, Stephen Wright talks to Lord Stevens, the former Metropolitan Police Commissioner who led Operation Paget, about the people who spread the conspiracy theories about Diana’s death, and why some are still not convinced to this day that her death was an accident.
