The latest series of BBC sci-fi favourite Doctor Who went out with a bang - and a surprise regeneration - a couple of weeks ago.
It marked the end of time travel for Rwandan-Scottish actor Ncuti Gatwa , who had played the 15th Doctor for under two years.
And it signalled an escalation of speculation about what is next for the programme.
There’s even talk of it being the end of the road for the iconic series, which has been suffering from tumbling ratings - Disney and the BBC, who co-own the frachaise, have yet to make a decision on whether a new series will be made.
If it is to continue, the bookies have an idea who might step into the main role - here are the 13 favourites to take over ownership of the sonic screwdriver, according to the experts at gambling.com.
