As a lifelong anti-nuclear activist, it should really have come as no surprise that Labour leader Jeremy Corbyn would refuse to authorise the use of a nuclear weapon as prime minister.
The Labour leader was asked on the Today programme if he would ever press the button launching a nuclear missile.
No, 187 countries don't feel the need to have a nuclear weapon to protect their security, why should those five need it themselves? We are not in the era of the Cold War any more.
I am opposed to the use of nuclear weapons, I am opposed to the holding of nuclear weapons. I want to see a nuclear-free world. I believe it is possible.
The comments sparked a backlash among his shadow cabinet - Corbyn's personal view is that the Trident nuclear deterrent should not be renewed - with shadow defence seretary Maria Eagle saying they were "unhelpful".
Meanwhile, prime minister David Cameron told BBC1's The Andrew Marr Show on a nuclear weapon: "There are circumstances that justify its use."
Corbyn's 'admission', the 70th anniversary of the nuclear bombs being dropped on Hiroshima and Nagasaki in August, and the Iran nuclear deal have put the issue to the fore once again.
This timely video, from Seeker Stories, is called 'The worst nuclear testing you've never heard of'. It details Soviet nuclear testing over many decades in Semipalatinsk, Kazakhstan, an area thought to be uninhabited but actually home to 1.5 million people.
The true extent of the testing only emerged after the Cold War, tonnes of radioactive material were just left behind, and it is thought up to 200,000 people suffered health consequences as a result.

Unsurprisingly, Kazakhstan is one of those 187 countries Corbyn mentioned as not having a nuclear bomb.
