Former 'Great British Bake Off' presenters and long-term TV partners Mel Giedroyc and Sue Perkins are set to star in the first sitcom together as a pair of hapless killers.

The duo are set to play two besties Fran and Jamie in the upcoming Sky One six-part comedy, who stumble upon a career of contract killing but aren't very good at it.

Called 'Hitmen', each episode follows the duo as they try to carry out their latest hit, working out of their scruffy van, only to be derailed by "incompetence, bickering, and inane antics".

Giedroyc’s Jamie is described as an "affable goof… content to spend her days hanging out with her best mate" while Perkins' "super sensitive" Fran "starts to question whether it’s really the life she wants".

Executive producer Myfanwy Moore said: "We are so excited to be working with the truly fantastic female comedy partnership that is Mel and Sue, who can brandish bullets and banter brilliantly in equal measure".

While Sky’s head of comedy Jon Mountague said he was excited about the new line up and said 'Hitmen' would "capture the chemistry of Mel and Sue and their playfulness in a scripted comedy world".

The series is written by Joe Parham and Joe Markham with some input from Mel and Sue. It's set to premiere on Sky One in 2019.
