A county Tyrone television watcher has thrown the TV series Dr Who into disarray after he worked out that the outer dimensions of the TARDIS in no way matches up to its inner measurements.

Diarmuid Dieselin, who claims to have worked on the finer detail of this explosive revelation for more that five years, has already written to the BBC asking for an apology for 55 years of hoodwinking the audience.

“It’s a disgrace. The box is about nine feet tall, maybe three and a half feet wide and deep. Yet inside the TARDIS there are many rooms and chambers as well as a massive console room. Do they think we are idiots?”

Although the BBC have yet to comment on the news, sources close to the broadcaster have hinted that they might stall the current series to rebuild the TARDIS so that it looks more like a hotel or change the plots completely and just have one small table and two plastic chairs inside it.

Mr Dieselin is currently assessing the supposed speed of the TARDIS which currently traverses the time vortex and can rematerialise in any destination or time. Early indications suggest he’s not pleased with his findings.
