Nicola Walker in The Split

Nicola Walker looks every inch the hotshot lawyer in first-look images from BBC drama The Split.

The actress, 47, plays divorce lawyer Hannah Defoe in the original series for BBC1 and SundanceTV.

The first-look images show Nicola clad in a white jacket and dark skirt, surveying the capital through an office with floor-to-ceiling windows.

The Split explores marriage and relationships through the personal and professional lives of the Defoes, a family of lawyers at the heart of London’s divorce circuit.

The six-part series mixes legal, relationship and family drama as Hannah, her sister Nina, played by Annabel Scholey, and mother Ruth (Deborah Findlay) negotiate scandalous affairs, big-figure settlements and fraught relationship battles at work, while navigating their own complicated lives at home.

The drama has been created and penned by Abi Morgan, whose credits include Baroness Thatcher film The Iron Lady, and the TV series set in a 1950s newsroom, The Hour.
