During the special This Morning edition reflecting on the days since the Queen’s death, Ms Willoughby said: “Like hundreds of accredited broadcasters and journalists we were given official permission to access the hall.
“It was strictly for the purpose of reporting on the event for millions of people in the UK who have not been able to visit Westminster in person.
“The rules were that we would be quickly escorted around the edges to a platform at the back.
“In contrast, those paying respect walked along a carpeted area beside the coffin and were given time to pause.
“None of the broadcasters and journalists there took anyone’s place in the queue and no one filed past the Queen. We of course respected those rules.
“However, we realise that it may have looked like something else, and therefore totally understand the reaction.”
She added: “Please know that we would never jump a queue.”
Meanwhile, the former England captain and multi-millionaire David Beckham was praised for queuing alongside members of the public for 13 hours on Friday to pay his respects to the late monarch.
