Following disappointing ratings, BBC One announced yesterday that the space drama will be moved from its current 9pm Monday slot to 10.25pm on Sunday nights from Episode 6.

Earlier this week, Richards wrote on Twitter: “We missed the target by definition if not enough people come to it. But I’m very proud of it, especially what still to come.”

He added yesterday, following news of the slot change: “To be fair it was struggling in slot. I’m pleased it will have some pressure taken from it and people can enjoy last eps.”

Richards also thanked fans for their support, saying: “Cultdom beckons. And keep watching hardcore because remaining eps great.”
