People have been left feeling a little baffled by the background of Prince Charles’ home as he gave a televised speech, having clocked a strange picture behind him – in which it looks as though someone has been ‘cut out’.

Prince Charles joined the throngs of people currently using video calls to communicate, having dialled in from his Scottish home in Birkhall to comemmorate the opening of the new NHS Nightingale Hospital with a speech.

But while the 71-year-old spoke about the hospital and thanked those who have made it possible, viewers at home were distracted by a small detail in the background of the shot.

One person tweeted: “Too busy looking at that mystery photo to listen to what Prince Charles actually said.”

Another asked: “Did Charles forget to put a picture in the frame? #PrinceCharles.”

A third added: “Dumb question – what is that frame behind #PrinceCharles that looks like someone was cut out of a picture?“

Someone else pondered: “Prince Charles currently giving a speech. Empty photo frame in the background? Is this for the lost siblings within the ranks?“

As everyone at home inspected his family snaps behind, Prince Charles referred to the new NHS Nightingale hospital as ‘an intensely practical message of hope at this time of national suffering’.

He said: “It is, without doubt, a spectacular and almost unbelievable feat of work in every sense, from its speed of construction – in just nine days as we’ve heard – to its size and the skills of those who have created it.”

The Royal – who recently recovered from coronavirus – added: “An example, if ever one was needed, of how the impossible could be made possible and how we can achieve the unthinkable through human will and ingenuity.”

The first of several such facilities planned across the UK, the temporary hospital opened today following just nine days of construction.

Having taken over London’s ExCel exhibition space – often used for large-scale events like Crufts and Comic Con – the hospital is able to hold up to 4,000 patients.
