PICK OF THE DAY

Poldark

9PM, BBC1 The battle for Sunday-night hearts and minds begins in earnest this weekend as BBC1 and ITV line up their big guns against each other. Victoria has had a head start on Poldark, but with Aidan Turner back as TV’s hunkiest hero, it’s sure to be ITV that ends up not amused in the ratings war. And the opening episode of Poldark is a belter, with a decidedly darker tone than before, as Ross is facing the hangman’s noose after the dramatic events on the beach at the end of series one. Can Demelza (Eleanor Tomlinson) help to clear her husband’s name?

Roald Dahl’s Most Marvellous Book

6.30PM, CH4 Charlie And The Chocolate Factory, The BFG, The Witches, Matilda, The Twits... Roald Dahl is the undoubted master of children’s literature. To mark the 100th anniversary of Dahl’s birth, David Walliams is joined by a host of celebrity fans to discuss the author’s ten bestselling books.

A Very British Deterrent

8PM, BBC2 Rooted in the tense events of 1957-62, this fascinating documentary tells the story of how Britain secured its place in the elite nuclear club. Using declassified secret files and personal testimony, the programme details the tortured process that led to the government securing the ultimate deterrent.

Speed With Guy Martin

This is the real Fast And The Furious.
