Once, during one of the jubilee tours, I was in the car immediately behind theirs and I watched Prince Philip telling the Queen a story. He kept her laughing for 20 minutes.
The Queen has well-informed opinions of many of her bishops and likes those who are straightforward and intelligent. Both she and Prince Philip believe Christianity is as much about forgiveness as morality.
Prince Philip was a funny man who liked to laugh and make others laugh.

Prince Philip is very intellectual. And Prince Charles is extremely well read.
The royals - all of them, especially Prince Philip and Prince Charles - have done outstanding work with the faith communities.
The Royal Family are not like you and me. They live in houses so big that you can walk round all day and never need to meet your spouse. The Queen and Prince Philip have never shared a bedroom in their lives. They don't even have breakfast together.

Was Prince Philip in love when he proposed to Elizabeth? At the time, he was a relatively penniless prince, with a rackety family and no home to call his own.
I've met Prince Charles and Prince Philip.

Once she had loved Prince Joffrey with all her heart, and admired and trusted her his mother, the queen. They had repaid that love and trust with her father's head. Sansa would never make that mistake again.
Several people have told me that Queen Elizabeth made slighting comments about Philip within their hearing, and referred to him - not entirely humorously - as 'the Hun.'
Prince Philip had formally 'retired' in the summer of 2017, a couple of months after his 96th birthday, because the Queen encouraged him to do so. She wanted to stop him 'pushing himself all the time'. She had become anxious about him.
