After audiences were left reeling by the collapse of Hannah and Nathan’s marriage at the end of series two, we join them again ten months on, following the two divorce lawyers as they negotiate their way through their own separation.

With Dee Koppang O’Leary (Bridgerton, The Crown) boarding as lead director, Abi Morgan will conclude the trilogy with the most heart-warming and heart-breaking series to date as we watch a divorce lawyer confronted with her own divorce. With Christie making a return combined with a shocking revelation, will Hannah and Nathan repair their broken marriage, or is The Split simply too deep to repair?
