Queen Elizabeth 'wasn't angry or upset' over Prince Harry and Meghan Markle's decision to take a step back from their roles as senior members of the royal family, he claims.
The Duke of Sussex, 38, sat down for an interview on Good Morning America, which aired in the US around 12pm in the UK today and gave royal fans a further insight into his life.
He suggested that the late sovereign's hands were tied when it came to helping him and his wife - and his grandmother didn't air her frustration at their 2020 departure plan as she "knew what was going on".
Harry's latest interview comes amid a string of TV appearances ahead of the upcoming release of his book Spare, which was leaked in Spain days before its release date.
In his latest interview, he told Michael Strahan how the Queen reacted when he broke the news of his and Meghan's decision to step back from their roles.
Harry told of his 'good' relationship with the late Queen, who died in September at age 96.
The Duke of Sussex also claimed the Queen "knew how hard it was" for himself and his wife Meghan Markle, who share children Archie and Lilibet together.
He said: "My grandmother and I had a very good relationship."
The Duke of Sussex added of his decision to step down from his senior royal role: "It was never a surprise to her, she knew what was going on, she knew how hard it was.
"She never said to me that she was angry – I think she was sad it had got to that point."
Harry went on to tell Good Morning America said he "genuinely" believes the British monarchy has a place in the 21st century, but it needs to modernise.
He added that there was no compromise with the family, which made him "really sad because I still to this day believe that this was entirely possible".
It comes after Prince Harry revealed how he heard of the Queen's death when he checked BBC News after he sadly was unable to get to Balmoral Castle in time to say goodbye.
The Duke of Sussex had been in the UK to attend the WellChild Awards in September, when the monarch fell ill.
In a race against time, he boarded a plane and flew north to be at her bedside.
“It was a message from Meg: 'call me as soon as you read this'. I checked the BBC webpage. My grandmother had died. My father was the King.
“I put on a black tie, stepped off the plane into heavy drizzle," he wrote, according to The Sun.
