In addition to this, they noted Prince Charles’s decision to make a trip to his father during a pandemic was “extraordinary”.
Ms Robinson added it was even more unusual as Prince Philip rarely has visits from the Royal Family while in hospital.
Mr Ship said: “With the Duke of Edinburgh, Prince Philip, the thing I think that got everybody worried wasn’t just the change of language that we got last week from the Palace.
“The language that was all about keeping him in as an abundance of caution and him only being in for observation.
Prince Philip health: Prince Charles and the Palace has caused more concern for Prince Philip’s health with their odd behaviour in the past week.
“Whereas this week them saying that he has got an infection and he is having treatment and he is not coming out for several days.”
In addition to this Mr Ship noted the significance of Prince Charles’ visiting his father.
He said: “This is coupled with an unannounced visit from Prince Charles on Saturday, this rather worried everybody about the seriousness of his condition.”
Ms Robinson added: “This is correct, the Duke of Edinburgh is 99 and to be 100 in June.
“Even when the palace talked about him going in with the abundance of caution, there is always some concern when we are talking about someone of that age.
“I think the visit made by his son the Prince of Wales on Saturday did rather concern us.
“It is quite unusual in normal times for him to receive visitors when he is in hospital.
“It seemed extraordinary in the middle of a pandemic.”
Prince Philip health: Saturday will mark the 11th night and the longest stay the Duke of Edinburgh has ever been in hospital.

Earlier this week, Buckingham Palace confirmed Prince Philip is “comfortable and responding to treatment” but is not expected to leave hospital for several days.
Royal expert Camilla Tominey has said the Palace have attempted to “dampen down any alarm”, however.
