Bradley Wash, Mandip Gill and Tosin Cole have been unveiled as Jodie Whittaker's co-stars when she becomes the 13th person to take on the lead role in Doctor Who.

The trio will appear as the Doctor's "companions" Graham, Yasmin and Ryan in the next 10-week series slated for autumn 2018.

Broadchurch and Trust Me star Whittaker will take over in the Tardis from Peter Capaldi when the Time Lord regenerates as a woman for the first time after the Christmas special.

Actor, comedian and quiz show host Walsh was widely tipped to be the Doctor's new assistant, although further details of his role are yet to emerge.

A fan of the show for 50 years, he told the BBC: "I remember watching William Hartnell as the first Doctor. Black and white made it very scary for a youngster like myself.

"I was petrified, but even though I'd watch most of it from behind the sofa through my fingers, I became a fan...

"Am I thrilled to be part of this whole groundbreaking new dawn for the Doctor? Oh yes!"

Gill, who has appeared in Hollyoaks and Casualty, said she was "over the moon" to be appearing in the hit programme, while Cole, who has had roles in Star Wars and EastEnders, said he was excited to be "jumping in this Doctor Who universe".

Writer Chris Chibnall described them as "three of Britain's brightest talents".

Mandip Gill and Tosin Cole will swap the streets of Chester for the inside of the Tardis when they join the cast of Doctor Who.

Both actors, who are joining the cast alongside Bradley Walsh and Jodie Whittaker's 13th Doctor, have spent time on Channel 4 soap Hollyoaks.

Cole, from south London, is also no stranger to the world of sci-fi, having made an appearance as Lieutenant Bastian in Star Wars Episode VII: The Force Awakens.

His first acting credit was in 2010 in the BBC drama The Cut, before a stint on EastEnders spin-off EastEnders: E20.

He joined the Hollyoaks cast in 2011 as Neil Cooper and also appeared in spin-off Hollyoaks Later.

More recently he has popped up in Holby City, Lewis and Versailles, before joining Doctor Who as Ryan.

He said: "I'm grateful and excited to be a part of this journey with the team. I'm looking forward to jumping in this Doctor Who universe."

Gill, 29, from Leeds, is also best known for her work on Hollyoaks as Phoebe McQueen, which was her TV debut in 2012.

She first appeared on the teen soap as troubled teen Phoebe Jackson, who was later adopted by the McQueen family, and bowed out from the soap in 2015 as a victim of the Gloved Hand Killer.

Since then she has appeared in Cuckoo, The Good Karma Hospital, Doctors and Casualty.

The actress, who will play Yasmin, said: "I am over the moon to be joining the Doctor Who family. This is an iconic show with an amazing fanbase and I look forward to everything that brings.

"Certain roles seem unattainable and this is one of those, so much so I didn't believe it to be true for the first few weeks.

"To be working alongside the likes of Jodie, Bradley and my old friend Tosin is thrilling.

"This show is worlds away from the work I've done previously and that's the part that excites me the most."
