The first teaser trailer for the fifth instalment of the hit BBC drama has arrived.

The teaser shows no signs of new characters yet, but it has been reported that we can expect a killer cast mate in Stephen Graham to take over the lead role, which was played by Thandie Newton the last time around.

A source told The Sun's Bizarre TV column: "It's a huge coup for Stephen, even as someone with his long CV."

Not only is Line of Duty one of the hottest dramas on TV but he's also following in the footsteps of a long line of high-profile signings, including Keeley Hawes and Daniel Mays.

"Producers are also thrilled to have him on board and have a very exciting story lined-up."

Just as he did in Little Boy Blue recently, he's sure to have viewers glued to their edge of their seats."

Graham will no doubt feel at home on set, reuniting with McClure, who he starred along side in the popular This Is England film and series.
