The allegations came after Swansea unexpectedly routed Notts County 8-1, with suggestions being made that the Notts County team had been bribed to lose the game convincingly following threats that the team would be forced to eat tripe if they won.
"We take these accusations extremely seriously, so I have myself fully investigated them just now and I can confirm that they are nonsense," Sir Norman said.
Confusion may have arisen because the TMB had previously advised tripe lovers to watch the match live on BBC1, in an attempt to persuade them not to watch a BBC2 show being broadcast at the same time.
Sir Norman said the episode demonstrated the old adage that there was no such thing as bad publicity, adding "In the event, we had nothing to worry about with the Back in Time For Tea programme. It seems to have piqued a lot of people's interest in tripe, which is always a good thing."
The allegations are a bizarre echo of an incident also involving Notts County and a team of looky-likeys that were first covered in the TMB Books publication, Forgotten Lancashire and Parts of Cheshire and the Wirral.
