Prince Charles has revealed the Queen has probably only got one television as he and his wife Camilla tour Northern Ireland.
Charles, 72, had an amusing exchange with a young boy who had turned out to see the royal at Donaghadee, as the boy asked him how many televisions his mother had.
"One I think," replied the prince. "And maybe one or two elsewhere as well, you never know."
The Queen, 95, has spent most of the last year living at Windsor Castle, which is where she usually spends weekends when she is on duty at Buckingham Palace.
Charles may have been referring to the Berkshire home in his answer as she is likely to consider that home at the moment.
However she spends her summers in Balmoral, and Christmas at Sandringham, where its known the family gathers around the television to watch her message at 3pm on 25 December.
The Queen has previously been reported to watch programmes like Downton Abbey, Emmerdale and even EastEnders. She also apparently has boxsets of the Doctor Who series.
In 2011, X Factor contestant Mary Byrne said the Queen had watched the talent show.
She told the Irish Independent: "She came up and spoke to me and said ‘you are the lady off the ‘X Factor’.
"I asked her did she watch it? The Queen said she watched it the next day so she must have recorded it."
Charles and Camilla, 73, are on a two day tour of Northern Ireland, and have spent time in Belfast and Co Down where they visited an outdoor market.
They were greeted by schoolchildren in Bangor before touring the market which is 98 years old.
Clarence House shared on Twitter that the royal couple looked at the range of local goods on sale including cakes, fish, fruit and vegetables and plants.
Charles then went onto the harbour town of Donaghadee, where he viewed stones with messages of hope, left during the pandemic along the harbour wall.
He elbow bumped well wishers who had gathered to see him, although details of the visit were not meant to be public.
Cathy McAllister, who lives nearby, said the visit boosted people's spirits.
"It was supposed to be kept quiet but in Donaghadee things get round quite quickly," she said.
"So it was a great turnout for him and such a lovely day - it really showcased the town at its very best."
Charles also stopped to stroke some of the pet dogs of well-wishers.
While Charles was at the harbour, Camilla went to Kilcooley Women’s Centre in Bangor where she visited a book club named in her honour.
The Duchess of Cornwall spent time with the Camilla Club, a book group meeting virtually having been inspired by her Reading Room initiative.
The duchess launched the Reading Room earlier this year, keen to share her love of reading more widely.
She chooses four titles each term and the authors share their thoughts as well as their favourite books, while Camilla fosters discussion about the themes with questions posted on an special Instagram.
She told the group: "It’s wonderful and being here I was able to tie it all in and come visit you all."
Camilla then went to visit the Horses for People centre in County Down, hearing about equine-assisted therapy.
The duchess, a horse lover, met June Burgess, the centre's founder and then spoke to staff members and people who use the services.
She viewed some of the horses during her final engagement of the two-day tour.
