Keeley Hawes and Richard Madden have begun filming a new BBC drama from the creator of Line of Duty.

Bodyguard is a six-part series from Jedi Mercurio and follows David Budd (Madden), a heroic but volatile war veteran now working as a Specialist Protection Officer for the Royalty and Specialist Protection Branch (RaSP) of London’s Metropolitan Police Service.

When he is assigned to protect the ambitious and powerful Home Secretary Julia Montague (Hawes), whose politics stand for everything he despises, Budd finds himself torn between his duty and his beliefs. Responsible for her safety, is he actually her biggest threat?

The series will also stars Gina McKee, Sophie Rundle, Vincent Franklin, and Rowena King.
