'Peaky Blinders' is moving from BBC Two to BBC One for its fifth season, according to showrunner Steven Knight.

The announcement was made at the Edinburgh Television Festival, where Knight also confirmed that a sixth and seventh season is coming with Cillian Murphy and the principal cast set to return. BBC's director of content Charlotte Moore was keen to point out that the move from BBC Two to BBC One will not blunt any of the show's edginess in order to make it more palatable for their audience.

As Knight explained to the audience at Edinburgh, "Peaky is a show nurtured and grown by the audience who have found us through word of mouth. Hopefully this move will help us reach even more people." The season just gone of 'Peaky Blinders' was BBC Two's most-watched drama of 2017 and was the highest-rated of the series so far.

As for the sixth and seventh season, no further details were given beyond Murphy and the cast's involvement. "We’ve talked to Cillian Murphy and he’s all for it, and the rest of the principal cast are in for it,” said Knight.

The fifth season of 'Peaky Blinders' begins in 2019.
