The pair were then joined by fellow This Morning presenters Eamonn Holmes and Ruth Langsford.

Holmes said: "Nobody should be embarrassed about their sexuality and it's fantastic you have spoken out and there will be so many people who have been strengthened by what you've said."

He added that he and wife Ruth would be "the first to stand by you" and that it was clearly a "weight off his shoulders".

Messages poured in from This Morning viewers who said they were in awe of the presenter's courage.

One said watching him speak on the show was the "bravest and most incredibly emotional thing", while another said their house fell silent as he told of his struggle - "you could literally hear a pin drop in here".

Phillip's full statement on Instagram

"You never know what's going on in someone's seemingly perfect life, what issues they are struggling with, or the state of their wellbeing - and so you won't know what has been consuming me for the last few years.

"With the strength and support of my wife and my daughters, I have been coming to terms with the fact that I am gay.

"This is something that has caused many heart-breaking conversations at home. I have been married to Steph for nearly 27 years, and we have two beautiful grown-up daughters, Molly and Ruby.

"My family have held me so close: they have tried to cheer me up, to smother me with kindness and love, despite their own confusion. Yet still I can't sleep and there have been some very dark moments.

"My inner conflict contrasts with an outside world that has changed so very much for the better. Today, quite rightly, being gay is a reason to celebrate and be proud.

"Yes, I am feeling pain and confusion, but that comes only from the hurt that I am causing to my family.

"Steph has been incredible - I love her so very much. She is the kindest soul I have ever met. My girls have been astonishing in their love, hugs and encouraging words of comfort.

"Both mine and Steph's entire families have stunned me with their love, instant acceptance and support. Of course they are worried about Steph, but I know they will scoop us both up.

"My friends are the best, especially Holly, who has been so kind and wise - and who has hugged me as I sobbed on her shoulder. At ITV, I couldn't hope to work with more wonderful, supportive teams.

"Every day on This Morning, I sit in awe of those we meet who have been brave and open in confronting their truth - so now it's my turn to share mine.

"This will probably all come as something of a surprise and I understand, but only by facing this, by being honest, can I hope to find peace in my mind and a way forward.

"Please be kind, especially to my family.

"Phillip"
