- She just has to follow the advice of her doctors and get some rest, and I think that's the important thing right now.
I think the whole country hopes she is recovering, he says to the British TV channel Channel 4.
The statement was made after doctors advised the 95-year-old monarch to take it easy for at least two weeks.
Official visits canceled
The queen was taken to hospital last week for a routine examination.
She has since canceled a two-day visit to Northern Ireland and her physical involvement in the UN climate summit in Glasgow, COP26, which begins on Sunday.
According to Buckingham Palace, the queen - who next year can celebrate 70 years on the British throne - will continue to do desk work and some virtual audiences.
But she will not participate in any official visits in the next two weeks.
Although, according to Buckingham Palace, the Queen is fully prepared to attend when the memory of British war veterans is to be celebrated on 14 November.
She is also expected to give a speech via video link at COP26, while her 72-year-old son, Crown Prince Charles, will give the formal introductory speech to the climate summit.
