London Calling: Cold War Letters (BBC4, 8pm)
BETWEEN 1955 and 1975, the BBC’s World service programme Letters Without Signature broadcast letters which gave voice to the silenced people of East Germany by inviting them to secretly write into a radio programme. Listeners wrote in their thousands.
This film examines the impact of the show on both the people of East Germany – who faced imprisonment if discovered – and the show’s producers in London. Cameras also focus on its mysterious presenter, Austin Harrison, who announced different postal addresses every few weeks at the end of the show.
Giri/Haji (BBC2, 9pm)
AN ambush on a Soho restaurant ends with the Mori brothers on the opposite sides of a frantic gun battle – and prompts a series of flashbacks in which Yuto relives the split-second decisions that brought him and Kenzo to this point.
Fourteen months ago, Yuto realised he was destined to always be bad when yakuza boss Fukuhara dispatched his best man, Jiro, to recruit him.
But he also realised that unlike his brother, Fukuhara believed in him. Crime thriller, starring Takehiro Hira, Yuko Nakamora and Kelly Macdonald.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
