On Tuesday, the monarch reportedly showed “slight signs” of a cold, but it is thought the symptoms are not Covid related.
The Queen was due to visit Northern Ireland which she was forced to cancel due to her health issues.

The Church Leaders’ Group released a statement upon hearing the Queen will not be visiting.
“We are very sorry to learn that it will not be possible for Her Majesty Queen Elizabeth II to be present for the Service of Reflection and Hope in Armagh tomorrow,” they said.
“We wish to convey to Her Majesty our good wishes and, in doing so, to acknowledge the significance of her commitment to the work of peace and reconciliation, which has meant a great deal to people throughout this island.
“We hope that tomorrow’s service will provide an opportunity to further that work, with an emphasis on our shared hopes for the future.”
