Holly Willoughby’s This Morning colleagues Alison Hammond and Rochelle Humes pay tribute to the star as he leaves the ITV show

Holly Willoughby’s This Morning colleagues have rallied behind her as she announced she has quit the ITV show with immediate effect.

The 42-year-old TV star confirmed on Instagram on Tuesday that she “will not be returning to the show”, just days after an alleged plot to kidnap and murder her was foiled.

She said it was “an honor just to be a part of this story” but she felt like she “had to make this decision for myself and my family.”

Holly’s Instagram post was flooded with supportive comments from her This Morning co-stars.

Alison Hammond, who has co-hosted with Holly since Phillip Schofield’s resignation earlier this year, said: “This is a very sad day” but reiterated she loved the presenter.

Clodagh Mckenna, another chef on the show, wrote: “Your star will continue to shine wherever you go ⭐️ You have given us all so much love and light, in front of and behind the cameras ♥️ I am so grateful for everything you have given me … I love you so much, dear, beautiful Holly, the sunshine of our days ♥️♥️’

Holly admitted that it was “such a hard goodbye” and thanked the network for its “support.”

She also thanked the “wonderful viewers” who she said had been “loyal, so supportive and great company” over the years.

Her exit from the show came after a former Pizza Hut was remanded in custody last week over an alleged plot to kidnap and murder Holly.

Gavin Plumb, 36, from Harlow, Essex, is accused of offenses including incitement to murder and incitement to kidnap in connection with the broadcaster, allegedly contacting a hitman in the US and booking flights for him.
