It’s been less than two years since Rwandan-Scottish actor Ncuti Gatwa was confirmed as the 15th Doctor Who - but rumours are rife that he’s set to quit the role.
His second season as the Doctor is set to come to a conclusion later this year, with no third season yet confirmed by Disney and the BBC, who co-own the frachaise.
Speculation has been growing as to who might take over the TARDIS in one of the biggest roles in British television.
Here are the 13 favourites, according to betideas.com.

5. Leo Woodall
Very much the man of the moment, Leo Woodall shot to fame in HBO series 'The White Lotus' and his since starred in 'One Day', 'Prime Target' and 'Bridget Jones: Mad About the Boy'. He's 12/1 to add Doctor Who to his rapidly growing CV. | Getty Images

6. Richard Armitage
Richard Armitage is no stranger to a big franchaise, having starred in Peter Jackson's film trilogy adaptation of 'The Hobbit'. He has an army of fans thanks to his lead role in television programme 'North & South' and is a leading narrator of audio books. He's also 12/1 to take over the TARDIS. | Getty Images for the NTA's

7. Harris Dickinson
Recently starring alongside Nicole Kidman in an eye-opening role in 'Babygirl', Harris Dickinson is 14/1 to tackle a more family-friendly role next. | Getty Images for BAFTA

8. Olly Alexander
As famous for his singing (as frontman of band Years & Years and the UK's recent Eurovision entry) as he is for his acting, Olly Alexander was one of the favourites to take over the role when it went to Ncuti Gatwa. Second time lucky? The bookies reckon he has a 16/1 chance. | Getty Images for Bauer
