HM Passport Office Backlog

I am grateful to the Minister for giving way to me. Much of the discussion so far has been about delays, and most of my cases are about delays. However, I have one constituent whose original passport and application have been lost by the Passport Office, and he stands to lose his holiday. It is now the subject of a police investigation. As my constituent is waiting for the second application to be processed, will the Minister clarify whether the 10-week clock starts again? What recourse is there for my constituent if he loses his holiday because the Passport Office lost his passport and application?
