The Prince of Wales contracted coronavirus in March and has admitted he was "lucky" he only experienced "relatively mild symptoms" of the virus. Royal expert Penny Juror told The Sunday Times has since claimed experience of Covid-19 has made him "able to understand people going through terrible times and show leadership" and it has boosted his profile in a positive way.
"That he caught the virus is one of the best things that could have happened," she said.
"It echoes the Queen Mother and King George VI being able to stand shoulder to shoulder with the public during the Second World War after Buckingham Palace was bombed."
She said that more people have "seen and listened" to Prince Charles during the pandemic - and that he has used his social media presence well during the coronavirus crisis.
"There are so many people who don't really get Charles, who don't know what he does," Ms Juror explained.
"But during the coronavirus, maybe because of the lockdown, more people have seen him and listened to him than perhaps they would during normal times.
"The pandemic has given him a platform and he has been masterful in the way he's responded and used that platform."
The Prince of Wales spoke to royal correspondent Rhiannon Mills about his fight against the disease in an interview with Sky News' After The Pandemic: Our New World.
He said: "I was lucky in my case and got away with it quite lightly.

"But I've had it, and I can so understand what other people have gone through.
"I feel particularly for those who have lost their loved ones and have been unable to be with them at the time. That to me is the most ghastly thing."
The royal biographer added that the Prince of Wales' social media posts are now reaching far more people, giving more people an insight on his work.
"He is a king in waiting, that's what he has shown himself to be," she added.

He shared a video address on behalf of Age UK, charity he is a patron of, on coronavirus' effect on older people.
In the footage he said lockdown is a "strange, frustrating and often distressing experience' and highlighted how this is an 'unprecedented and anxious time in all our lives".

He also shared one of his favourite recipes for "cheesy baked eggs" in honour of British cheesemakers.
At the time, he was celebrating VE Day by reading an excerpt from grandfather George VI's diary.
In April, Prince Charles championed sustainability and environmental knowledge in a special post for Earth Day.
He wrote: "It is increasingly clear that when we care for our planet we fundamentally care for ourselves."
