But we could be waiting a while longer as producer [Jane] Tranter has confirmed that, once the 26 episodes that Disney initially commissioned have aired (which include the spin-off), "then, and only then, does Disney+ have to make a decision about whether or not they want to do more".

She added to The Royal Television Society: “I imagine, at a time when Disney are having huge cuts themselves, and there have been slashes in programme budgets, they’re looking to take their time to balance everything out and decide what they want to do."

However, she went on to say: “At its heart, it’s a BBC show and it will keep going, one way or another."
