Martin McGuinness

I lost a lot of friends at the hands of the British Army. The person who actually introduced me to my wife, Colm Keenan, was murdered by the British Army. He was a member of the IRA, but he was unarmed.

Obviously, Ian Paisley and I were regarded as very bitter opponents. When we decided in March 2007 to govern together, both of us understood that we weren't going to change our views but that we had to work with one another if we were to end the conflict and move forward.

Prime Minister Cameron says he wants to be the greenest government ever, but the definition of green is immature... I don't deny for a moment that CO2 is a greenhouse gas, but there are so many other factors that affect climate. It is more complicated than the computer models that we are using. What the truth is, nobody knows.
