When will 'Best Interests' be on BBC1? 

There is no official release date yet for the four-part drama yet, but as soon as we hear more we'll let you know! 

What's the plot of 'Best Interests'? 

A BBC synopsis reads...

"This is a story of a family driven apart by having to make choices no parent would ever want to make. Andrew and Nicci’s daughter, Marnie, has a life-threatening condition. The doctors believe it is in her best interests to be allowed to die, but her loving family disagree. And so begins a fight that will take them through every stage of a legal process, as they struggle to contemplate this huge decision. Who decides? And in whose best interests will it be?"

What does Jack Thorne say about the four-part drama? 

“As a parent of a three year old I've looked at the cases in the media about 'best interests' with some fascination and a little dread," he explains. "When the worst happens, how do you keep your head when everything around you feels wrong? We are going to try and tell a nuanced story that talks about this issue from all sides. I'm so happy to be working with Piers Wenger and the BBC again and to be part of the great folk at Chapter One Pictures. ”

Meanwhile Piers Wenger, Controller of BBC Drama, says: “This heart-breaking story delves deep into the inner turmoil these two parents experience when faced with their worst nightmare. Jack Thorne’s talent for tackling the most complex and challenging real life stories with consideration, wisdom and vision will make this a series to remember.”
