Speaking about the BBC's Once Upon A Time, the broadcaster's Chief Content Officer said: 'Once Upon a Time is a wonderful celebration of everything the BBC stands for: imagination, connection and storytelling for everyone.
'Across the year, we're bringing audiences a rich mix of programmes and events that highlight the joy and importance of reading at a time when it matters more than ever, and inspire families to discover new stories, revisit old favourites and share those moments together.
'Working with partners like the British Library, we're proud to shine a light on the extraordinary power stories have to help us escape, to comfort us, and to connect us with each other. Whether you're picking up a book, visiting your local library or simply enjoying a story at bedtime, we hope this celebration encourages everyone to find a little magic in reading this year.'
Last month Claire revealed she gave up caffeine after .
She said she had suspected something was wrong when she continued to lose weight.
Claire said she 'didn't know what was going on' so sought medical attention, where she was told she had a parasite in her system.
Appearing on the latest episode of Table Manners with Jessie and Lennie Ware, Claire revealed she picked up the parasite whilst in Morocco.
She explained: 'At least five years. And they travel as a pair. I got told by the doctor, gross, absolutely rank. It's disgusting anyway.
'So that's why I gave up caffeine. Because I had to give it up. I basically had to go on this diet, and because I didn't want to take, like, really hardcore antibiotics and stuff like that, I took all this little gross stuff, and part of that was giving up caffeine.'

Claire also revealed she has given up gluten and sugar, owing to an autoimmune condition which results in inflammation.
She said: 'This is my big secret, I feel like I'm in The Traitors or something, and I'm letting everyone know that I'm related to someone!
'So I don't actually eat gluten or sugar [..] except when I go out for dinner. It doesn't have an impact on me.
'It's just because I have an autoimmune condition, so I should avoid anything which causes more inflammation.'
