Queen Rania of Jordan has praised the Duke of Edinburgh for being a "constant anchor" for the Queen

Speaking about the challenge Prince Philip faced, she told ITV News: "Being married to someone who is under so much pressure means you have to do whatever you can to try and alleviate some of that pressure. Even if that’s by being a distraction.

"The wellbeing of your spouse eventually has an impact on how well they can carry out their duties."

She added that there "must have been times when it wasn't easy for him".

Meanwhile, Prince Charles has admitted he will miss the Duke of Edinburgh "enormously".

The 72-year-old royal praised Prince Philip for his "remarkable, devoted service" to the Queen, his family, the country and the Commonwealth.

He said: "I particularly wanted to say that my father, for I suppose the last 70 years, has given the most remarkable, devoted service to the Queen, to my family and to the country, but also to the whole of the Commonwealth.

"As you can imagine, my family and I miss my father enormously."

Prince Charles also thinks the Duke of Edinburgh would've been "amazed" by the reaction to his passing.

He said: "My dear Papa was a very special person who I think above all else would have been amazed by the reaction and the touching things that have been said about him, and from that point of view we are, my family, deeply grateful for all that.

"It will sustain us in this particular loss and at this particularly sad time."
