Unreported World
7.30pm, Channel 4
“Narco-submarines” are homemade vessels that carry tonnes of drugs across the Atlantic from Latin America. According to this report from the journalist Guillermo Galdos, the number of seizures of such vessels is on the rise in Spain – more than 90m tonnes were confiscated by the authorities last year. Galdos follows customs officials as they try to track the narco-subs, discovers a network of seasoned smugglers in Galicia and speaks to a fisher who is also a cocaine courier. Hollie Richardson

Gardeners’ World Winter Specials
8pm, BBC Two
If you are wishing you had given your lawn one last mow, be prepared to be put to shame by the year-round devotion shown by Monty Don and the team. Carol Klein looks at shrubs for the chilly months, while Nick Bailey visits a wild garden that promotes biodiversity. There is also a pruning masterclass and some allotment love. Hannah Verdier
Junior Taskmaster
8pm, Channel 4
Another gang of spirited youngsters report to the Taskmaster (Rose Matafeo) and her assistant (Mike Wozniak) in the second heat of this junior version. There are some mind-blowing inventive – if completely useless – solutions as the kids try to serve a mocha to a dummy, make a paper plane and cram biscuits through a sieve. HR
RuPaul’s Drag Race Down Under
9pm, BBC Three
Michelle Visage has taken over from RuPaul as the host for season four, but otherwise it is very much business as usual in the festival of catty fabulousness. After last week’s tribute to Olivia Newton‑John, the remaining queens are tasked with delivering some rather less respectful celebrity impressions. Graeme Virtue
The Last Leg
10pm, Channel 4
Another acerbic look at the week’s news. After the US presidential election, Adam Hills, Josh Widdicombe and Alex Brooker are aided in their quest to determine whether or not it is OK (#isitok) by the insights and opinions of the Irish panel-show veteran Dara Ó Briain and the Lebanese-American standup Janine Harouni.

Dune: Part Two (Denis Villeneuve, 2024), 11.05am, 8pm, Sky Cinema Premiere
It was a smart move to spin out the latest adaptation of Frank Herbert’s fantasy saga. Having emerged triumphant from the first instalment, where he took the time to establish its complex universe, Denis Villeneuve can now concentrate on the changing nature of Timothée Chalamet’s desert-planet messiah, Paul Atreides, and his relationship with Zendaya’s native warrior, Chani. It’s equally spectacular, but has an air of foreboding about the prophesied victory that adds depth to the clash of cultures. Roll on part three! Simon Wardell
