The 95-year-old queen took two virtual appointments from Windsor Castle, meeting with Gunn Kim, the Korean ambassador to Britain, and Markus Leitner, the Swiss ambassador to the United Kingdom.
The engagements were the queenâ€™s first scheduled meetings since Oct. 19, when she hosted a reception for the Global Investment Summit at Windsor Castle. She spent part of the following day in the hospital for what a spokesperson described as â€œpreliminary investigations.â€
The queen had planned to visit Northern Ireland last Wednesday and Thursday, but the palace announced at the last minute that the trip had been canceled, saying Elizabeth had â€œreluctantly accepted medical advice to rest for the next few days.â€
â€œFollowing medical advice to rest for a few days, The Queen attended hospital on Wednesday afternoon for some preliminary investigations, returning to Windsor Castle at lunchtime today, and remains in good spirits,â€ the spokesperson said. The palace didnâ€™t elaborate.
Nicholas Witchell, the BBCâ€™s royal correspondent, questioned the palaceâ€™s disclosures about the queenâ€™s health. He said on BBC â€œBreakfastâ€ last week that the media â€œwas led to believeâ€ that the queen was resting at Windsor Castle, when she was really in the hospital.
â€œSo, we werenâ€™t given the complete picture then. And one can understand the palaceâ€™s perspective on this,â€ Witchell said. â€œThey would say that the queen is entitled to patient confidentiality, to medical privacy and that sort of thing, notwithstanding that she is the head of state and that millions of people in this country and around the world will be concerned.â€
Witchell added that because reporters â€œwerenâ€™t given the complete picture,â€ the palaceâ€™s reassurance that the queen was â€œback at Windsor Castle undertaking light dutiesâ€ and â€œin good spiritsâ€ is subject to question.
â€œThat would certainly be in line with her stoical character, but thatâ€™s a phrase thatâ€™s a little bit of a cliche now,â€ Witchell said. â€œWe must hope that we can place reliance on what the palace is telling us.â€
