Media regulator Ofcom has revealed it is to investigate an absence of swearing in the Monty Python reunion show after dozens of fans complained of excessive ‘cuts’ and ‘censorship’.

The unusual state of affairs comes amidst claims the ageing comedy act have watered down their performance following the intervention of overzealous censors.

Contrarily however some fans actually complained that the pared down show was still too rude, forcing Ofcom to investigate both angles. In a statement the regulator said: “After receiving complaints about the broadcast of the most offensive language before the watershed, Ofcom is investigating a live performance of Monty Python on Gold.

“All our licensees are required to comply with our broadcasting rules, which make clear that the most offensive language cannot be shown on television before the watershed.

"As a post-transmission regulator, we are not involved in editorial decision-making and can only investigate programmes or take action against any channel after a programme's broadcast."

John Cleese, Michael Palin, Eric Idle, Terry Gilliam and Terry Jones were reunited for a series of gigs at the O2 Arena, including several raunchy routines and swearing.
