Colin Brazier told GB News that it remains important for the Royal Family and the Queen to be seen in person in Britain. He added that Meghan Markle and Prince Harry's online presence is better for reaching a bigger audience such as in the US.

       Mr Brazier said: "The Queen, famously, once said she had to be seen to be believed but there are different ways of being seen.

       "Harry and Meghan seem to think the occasional spectacular TV interview, or Netflix series, or internet webinar will do it.

       "And certainly, in a vast country like America, reaching an audience in person is hard to do.

       "But in Britain it’s feasible. A YouGov study in 2017 found that the Queen, over the course of her long reign, had been seen by 20 million Britons.

       "20 million subjects who see her and then tell their family and friends all about it.

       "That 20 million undergoes a compounding effect because, when you meet the world’s most famous woman, you want to tell people about it."

       He continued: "It’s surprisingly hard work, the walkabout. In 2019 Prince Charles alone did 521 public engagements. It involves a lot of smiling and listening.

       "The Sussexes want to tell stories, not hear them.

       "They might reason better one interview with the Queen of American TV, than dozens of functions with another Lord Lieutenant. But on our small island, seeing can still mean believing.

       "For me, better the Windsor walkabout than the Sussex woke-about any day."

       Mr Brazier also discussed the demographic of those more likely to support republicanism in the UK.

       He said: "To the dismay of abolitionists, the British monarchy remains enduringly popular.

       "But the love is not evenly spread.

       "For one thing, the young are less fervent than the old; a division that has deepened since the Harry and Meghan interview with Oprah Winfrey.

       "And the Palace has another problem. Scotland is more inclined to republicanism than England.

       "Not by much, but enough to give courtiers sleepless nights, especially with another independence referendum looming."
