The BBC’s flagship political debate programme had a reduced line-up after a Conservative MP got stuck on a train and missed the show.
Liz Truss tweeted that she would be unable to make it to the studios in time owing to a trespasser on a railway line that had curtailed her service.
The Chief Secretary to the Treasury tweeted: “Very sorry not be able to make @bbcquestiontime tonight.
“Stuck on a train due a trespasser on the line. Was looking forward to talking about our Budget tax cuts and boost for business.”
She added the hashtag #audienceofnone.
The show, airing on BBC One at 10.45 pm, was being filmed in Clacton-on-Sea in Essex, this week.
The other panellists who made it safely to the recording include Kate Andrews, of the Institute of Economic Affairs, comedian Shappi Khorsandi, journalist Anne McElvoy and Labour MP Andy McDonald.
David Dimbleby has announced he will be quitting the show after 25 years in the presenter’s chair.
