Sir Tim Smit co-founded the Eden Project in Cornwall in 2001. The Dutch born businessman is also known for restoring the Lost Gardens of Heligan with John Nelson. It's 25 years since these gardens were restored to their former glory. This week the Eden Project launched a new company Eden Project International Ltd (EPIL) to establish Eden projects with international partners around the world. Eden Project International is currently working on three projects in China and others in Australia and New Zealand.

John Gordon Sinclair is an author and actor, best known for playing Gregory in Bill Forsyth's film Gregory's Girl. In 2012 he turned his attention to writing crime novels and his current book, Walk In Silence, is the story of lawyer Keira Lynch who is caught up in the murky Albanian underworld. As an actor Gordon was nominated for a BAFTA for Best Newcomer for Gregory's Girl and his first outing in London's West End in She Loves Me won him a Best Actor Olivier award. Walk in Silence is published by Faber and Faber. Gordon features in the television drama Diana and I which will be broadcast on BBC Two later this year.

Comedian Sophie Willan's new show Branded explores why she feels like a well-travelled alien - fitting in with no particular class or culture but still constantly being put into boxes by others. Branded by her working class background, her gender, her ambition, and her unapologetic 'Northerness', she explains the misunderstandings she's experienced in different environments. Her previous show On Record tackled the story of her childhood in care and the impact of getting access to her case files at 23. Branded is at the Pleasance Courtyard: Bunker 2, Edinburgh.

Andy Baxendale is a sweet consultant who features in the BBC Two series the Sweetmakers which explores the life of confectioners in late 19th and early 20th century England. This was a time when cheap sugar meant sweets for every class in society and the modern brands that we still know and love today were created. Using period equipment, original recipes and authentic ingredients, Andy and his fellow confectioners recreate sweets of the past and discover the adulterants and toxic colours used in sweets, the Quaker families who dominated confectionery, and the poignant letters sent back from the First World War trenches. The Sweetmakers is broadcast on BBC Two.
