Prince Philip Still Hospitalized, Son Edward Says He's 'Better'

When asked if his father was frustrated in the hospital, Edward said he was. 

"I think that gets to all of us, and then, you can only watch the clock so many times, and the walls are only so interesting," he admitted.

"We've had some brilliant and lovely messages from all sorts of people, and we really appreciate that, and so does he," the early added. "I've been passing them on. It's fantastic, thank you." 

Buckingham Palace released a statement that said Philip would remain in the hospital for several days.

"The Duke's admission is a precautionary measure, on the advice of His Royal Highness's Doctor, after feeling unwell. The Duke of Edinburgh remains at King Edward VII's Hospital, where he is receiving medical attention for an infection. He is comfortable and responding to treatment but is not expected to leave the hospital for several days," it read.

Sources close to the palace confirmed to Reuters that the duke's illness was not related to COVID-19.
