One person Piers can count on for support is his ITV colleague, Lorraine Kelly.
Asked whether he should lose his job over his comments, she told PA: “Of course not. Of course not. It’s ridiculous. But don’t you imagine he is not revelling in all the attention – because he is.
“Actually, he is making a very good point. Whether you agree with someone or not, you can’t have a situation where we are going to shut people down.
She added: “He’s doing it with his tongue firmly in his cheek, of course.
“When he actually said, ‘We are going to debate whether or not I am going to fired,’ and of course my response was: ‘From a cannon?’”
Piers has courted controversy on a number of occasions on GMB with his comments on gender fluidity.
Last month, he said he identified as a “two-spirit penguin” following the news that a baby penguin at London Aquariam would be raised gender neutral by a lesbian penguin couple.
The aquarium said this was “completely natural”.
