After losing her screen sidekick of 14 years, Willoughby was then embroiled in a horrifying kidnapping plot by Gavin Plumb, 36, of Essex, who allegedly planned to snatch the mum of three after contacting a “hitman” in the US and making a restrain kit.
Last week, officers are said to have found chloroform, cable ties, a blindfold and ropes at his home when they raided it.
Plumb was arrested by Essex Police on October 4.
He appeared in court two days later, accused of soliciting to commit murder and incitement to commit kidnap.
Detective Superintendent Rob Kirby said: “This was an extremely fast-paced investigation, with many of our officers and national partners working overnight to secure these charges.
“The safeguarding of any victim is paramount and we will continue to prioritise this and working with the Metropolitan Police Service as the investigation proceeds.”
Willoughby was put under 24-hour surveillance when the alleged plot came to light.
Plumb, who has a child, has been working as a security guard at the Pinnacles Shopping Centre in Harlow and, before that, was a kitchen assistant at Pizza Hut until 2012.
After Willoughby’s shock exit from the show, Kevin Lygo, managing director of media and entertainment at ITV said: “We are sad that Holly is leaving This Morning, but respect her decision, which we know will have been extremely difficult for her to make.
“Holly is one of the best-loved, respected and most accomplished broadcasters in the UK.
“She has been at the heart of This Morning for the past 14 years, and she is adored by our viewers. Holly has brought her unique brand of warmth, energy, humour and fun to one of the country’s most popular daytime shows, and everyone on the programme will miss her enormously.
“She remains a much-loved member of the ITV family and we look forward to continuing to work with her in the future.”
Willoughby has received a wave of support after details of the alleged plot emerged.
On top of quitting her job on the breakfast show, she pulled out of a red carpet event in London this week.
Former co-star Philip Schofield also commented: “I was so sorry to hear about everything going on with Holly and I wanted to send my best to her and her family and to all of you”.
