Hit TV comedy Fleabag is returning – after its creator Phoebe Waller-Bridge dreamt up a new idea on a bus.

But the second series of the Bafta-winning series will not air until 2019.

Waller-Bridge, who was rumoured to have landed the role of the new Time Lord in Doctor Who before Jodie Whittaker was announced for the part, said it had taken a while to think of how to bring the show back.

“So that’s what has been taking us so long and me so long, to decide whether or not we’re going to do it again. And then I was on a bus and had an idea! So we’re really, really excited.”

She added in a statement: “I asked myself if Fleabag has more to say and frankly she hasn’t shut up since.

“Series two will be a whole new adventure, and I’m beyond thrilled to be coming back.”

BBC controller of comedy Shane Allen said: “Fleabag signalled the arrival of a hugely distinctive writer with the mesmerising performing talent to match.

“Phoebe’s career has shot up like a firework display in the last year and the show has been rightly hailed as a modern classic. It’ll be thrilling to see where she takes the character in the next series.”

Producer Lydia Hampson said: “It’s quite a long wait, but it’s happening.”

Waller-Bridge penned the comedy about an angry, cash-strapped, grief-riddled, porn-watching young woman trying to come to terms with a recent tragedy.

Producers said the new BBC Three series would “follow Fleabag through many more outrageous exploits”.
