I am afraid that my advice says that the hon. Gentleman’s amendment widens the remit rather than closing it down. Perhaps he should go back and look at precisely what he is proposing. It is clear that the Secretary of State will still be required to reopen a formal investigation where there are grounds for suspecting a miscarriage of justice. It is also worth pointing out that what we are talking about has no impact on the work of the marine accident investigation branch; that is completely separate to this issue.
The hon. Member for Hayes and Harlington (John McDonnell) asked whether there would be regulations for marine investigations. The answer is no, there would not be regulations. That is something that would be implemented. We have set out the circumstances in which we would expect the Secretary of State formally to reopen an inquiry. We would of course consider any specific requests that were received from relatives or trade unions that were affected by that decision-making process. The measure would come into force two months after Royal Assent.
