The city of Copenhagen is a climate crime scene tonight, with the guilty men and women fleeing to the airport in shame. World leaders had a once in a generation chance to change the world for good, to avert catastrophic climate change. In the end they produced a poor deal full of loopholes big enough to fly Air Force One through.

I first met Nelson Mandela when I was in my late 20s, in 1993. I was helping facilitate an African National Congress (ANC) workshop to plan its media strategy. I went down to meet him for the first time and you know me I got stupid... I just choked. I said, "Hello Madiba, it's a real honour to meet you," and I couldn't get another word out.

I think even though he [Nelson Mandela] was feted and praised as he was, he always was at pains to say, I'm a human being.

I was 15 years old when I first heard the name Mandela, or Madiba, as he is fondly known in Africa. In apartheid South Africa he was public enemy number one. Shrouded in secrecy, myth and rumour, the media called him 'The Black Pimpernel'.

The Social License is fundamentally about accountability to people and not just powerful interests. John Morrison’s book reminds all organizations – governments, business and civil society – to focus on the legitimacy of their own actions.

Nelson Mandela once said "I can't help it if the ladies take note of me; I'm not going to protest."
