jury of six women and five men. Lord Justice Baker delivered a lengthy opening statement giving general instructions to the jury and introducing the evidence. The BBC reported that Mohamed Al-Fayed, having earlier reiterated his claim that his son and Diana were murdered by the Royal Family, immediately criticised the opening statement as biased. The inquest heard evidence from people connected with Diana and the events leading to her death, including Rees-Jones, Mohamed Al-Fayed, Paul Burrell, Diana's stepmother, and the former head of MI6. Lord Justice Baker began his summing up to the jury on 31 March 2008. He opened by telling the jury "no-one except you and I and, I think, the gentleman in the public gallery with Diana and Fayed painted on his forehead sat through every word of evidence" and concluded that there was "not a shred of evidence" that Diana's death had been ordered by Prince Philip or organised by the security services. He concluded his summing up on Wednesday, 2 April 2008. After summing up, the jury retired to consider five verdicts, namely unlawful killing by the negligence of either or both the following vehicles or Paul; accidental death or an open verdict. The jury decided on 7 April 2008 that Diana had been unlawfully killed by the "grossly negligent driving of the following vehicles [the paparazzi] and of the Mercedes driver Henri Paul". Princes William and Harry released a statement in which they said that they "agree with their verdicts and are both hugely grateful". Mohamed Al-Fayed also said that he would accept the verdict and "abandon his 10-year campaign to prove that Diana and Dodi were murdered in a conspiracy". The cost of the inquiry exceeded £12.5 million, the coroner's inquest cost £4.5 million; a further £8 million was spent on the Metropolitan Police investigation. It lasted 6 months and heard 250 witnesses, with the cost heavily criticised in the media. In his memoir, Diana's younger son Prince Harry mentions how the summary conclusion of investigations into his mother's death was "simplistic and absurd." He writes that even if the driver "had been drunk, he wouldn't have had any problem driving through such a short tunnel." He questions why the paparazzi that had been following her and the people who sent them were not in prison, unless it was all due to "corruption and cover-ups being the order of the day?" Harry claims
