A new Channel 5 documentary looks into the plot of Gavin Plumb who planned to kidnap and murder Holly Willoughby – although the presenter ‘refused’ to take part in the show.

Security guard Gavin Plumb, from Essex, had planned to kidnap the TV star, with Essex police explaining that Plumb had “developed an obsession with Holly Willoughby over a number of years”.

Now, Channel 5 has made a documentary titled The Plot to Kill Holly Willoughby – which airs tonight – uncovering Plump’s horrifying acts.

Although Holly will not appear in the program herself, there will be commentary from journalists and criminal psychologists.

The TV presenter refused to participate in the documentary, which was originally set to be titled, Stalking Holly Willoughby. With a source telling The Sun: “Producers are ploughing ahead in making it regardless’ because they know it will be a ‘ratings hit’.”

“She declined to be interviewed by producers about the ordeal and her reps informed Channel 5 she wasn’t technically stalked so their title is incorrect. There is also concern that the events will be sensationally dramatised for effect.

“It’s an awkward move, as it’s not their story to tell.”

In July of last year, Plumb was convicted after spending nearly ten years consumed by a disturbing obsession with her. He had participated in multiple online forums – including one named “Abduct Lovers” – where he shared detailed plans to abduct the presenter from her home.

During his sentencing, jurors were presented with evidence of conversations between Plumb and a man known as “Marc”, in which they exchanged graphic details about the planned crime.

Plumb was ultimately caught when an undercover US officer infiltrated the Abduct Lovers forum and became so alarmed by his messages that the information was passed onto the FBI.

The show will highlight Plumb’s plans showing thousands of images he had of Holly, along with how he tracked her movements, researched her home and security arrangements and had recruited other men to help turn his sick fantasies into reality.

Showing that the men were planning on abducting her from her house in London, using chloroform to knock out her husband and use her children as leverage. Taking the TV star to a remote location to sexually assault her and then murder her.

When Holly learnt of the plans, her life was turned upside down as she withdrew from public life until the police built a case against Plumb. She waived her right to anonymity in connection to the charges against Plumb, but left This Morning after her 14-year stint on the show following the offences.

Plumb was given a life-sentence and ordered to serve a minimum of 16 years in prison for his crimes.
