Meet the cast of the BBC's political thriller Roadkill

Here are all the characters you'll meet in the drama, as well as the actors who play them.

Hugh Laurie plays Peter Laurence MP

Who is Peter Laurence? A Conservative cabinet minister. As Hugh Laurie describes him: "He begins the story at mid-cabinet level as Transport Secretary and has ambitions to move up the greasy pole. The story is in some regards about the price he is prepared to pay to get to the top position and the price that he forces everyone else to pay, principally his family but also those who pledge their loyalty to him. He is a man who is relatively free of the gravity of guilt and whose life mission is to keep moving forward and not to look back."

What else has Hugh Laurie been in? Quite a lot of things. With Stephen Fry, he was part of the comedy double act Fry and Laurie; he's also starred in Jeeves and Wooster, Blackadder, Sense and Sensibility, Avenue 5, The Personal History of David Copperfield (as Mr Dick), Catch-22 (as Major de Coverley), Veep, and of course the long-running American medical drama House – which won him two Golden Globes and a handful of Emmy nominations. He also won a Golden Globe for playing Richard Roper in the John le Carré series The Night Manager, and he has a musical career as a blues musician.

Helen McCrory plays PM Dawn Ellison

Who is Dawn Ellison? The Conservative Prime Minister, who is therefore Peter Laurence's boss. But as Helen McCrory puts it, "she doesn't realise how dangerous he is. I think she realises that he is popular and that he is highly ambitious, as she is, and he is without scruples, as she is. But what she doesn't realise is how many supporters he has."

What else has Helen McCrory been in? While Helen McCrory plays the Prime Minister in Roadkill, we've previously seen her playing the PM's spouse – specifically, Cherie Blair in 2006's The Queen and 2010's The Special Relationship. Many will know her best as Polly Gray from Peaky Blinders; others will know her as Narcissa Malfoy from the Harry Potter movies.

At the beginning we meet her doing what regularly she does which is win cases. She is very competent and very good at her job.

Iain de Caestecker plays Duncan Knock

Who is Duncan Knock? Peter Laurence's special advisor. Iain de Caestecker says: "Duncan is ambitious and he’s married to his job; it definitely occupies a lot of space in his mind, so I think a huge part of his identity is what he does. Being a special advisor is kind of a bit of a controversial role as they work within a governing party and although they aren’t actually voted in by the public, they are politically motivated and do have a political agenda. So he’s probably worked his way up with Peter the past few years and he knows where the bodies are buried, but he’s also complicit in that. He sees Peter as his ticket to the top as well. As much as I think he admires Peter in a big way and looks up to him, he's got his eyes on his own prize as well."

What else has Iain de Caestecker been in? He is perhaps best known for playing Leo Fitz in Agents of S.H.I.E.L.D., or for playing Adam Barlow in Coronation Street back in the early noughties. Most recently he played Young Douglas in the TV series Us; other credits across TV and film include Overlord, Not Another Happy Ending, The Fades, Lip Service, Shell, Lost River, and In Fear.
