New images have offered a first glimpse at the finale of BBC thriller Vigil.

One of the pictures shows Stephen Dillane’s character Rear Admiral Shaw holding a press conference while flanked by military officials.

Two other shots from the submarine drama show Matthew Doward, played by Lorne MacFayden, in his Royal Navy uniform.

At the end of last week’s programme he left Suranne Jones’ character DCI Amy Silva to drown in a torpedo tube as he was revealed as a traitor.

The BBC One drama has been made by the production company behind Line Of Duty and Bodyguard.

It tells the story of DCI Silva leading an investigation that uncovers a conspiracy around national security after a sailor is found dead on a submarine.
