Holly Willoughby, one of Britain’s most high-profile television personalities, announced Tuesday that she is stepping down from her presenting role on the ITV network’s flagship daytime program “This Morning,” days after a man was charged in connection with an alleged plot to kidnap and murder her. Willoughby, who has been off air since Thursday as a result of the security scare, said on Instagram that she is standing down after 14 years in her role presenting “This Morning”, a magazine program that mixes celebrity interviews and entertainment news with discussions about current affairs. “I have let ITV know today that after 14 years, I will not be returning to This Morning," the 42-year old said.
