We've made too many compromises already; too many retreats. They invade our space and we fall back. They assimilate entire worlds and we fall back. Not again! The line must be drawn here! This far, no further! And I will make them pay for what they've done!

I do what I do in my mother's name because I couldn't help her then. Now I can.

I've been a witness to unfairness in society all my life. To the conditions under which my mother worked all her life, working in an industrial weaving shed in the north of England. And it has been this feature of unfairness that has motivated me in all of my political thinking.

I would like to see us get this place right first before we have the arrogance to put significantly flawed civilizations out onto other planets, even though they may be utterly uninhabited.

I know it feels like two steps forward and one step back, but we are making progress. In my lifetime, I have lived through one World War, I have lived through the end of Apartheid in South Africa, the pulling down of the Berlin Wall. I have experienced what I never thought I would have experienced, which is a pretty workable peace in Northern Ireland, and I experienced a unified Europe - until the Conservative government got its hands on the idea that in order to appease a few back-benchers they would hold a referendum, what a disastrous idea.

During my time we had two chairman of the joint chiefs of staff, at different times of course, on the bridge, both of whom asked my permission to sit on the captain's chair.

I've been in politics all my life. In 1945, I committed my first act of civil disobedience during the election campaign for the first post-World War II general election, when the Labour Party, to everyone's amazement, ousted the Conservatives. I refused to obey the instructions of a policeman, and as a result, almost got a belt around the ear, because those were the days when policemen could hit children and nobody cared, they thought it was probably good for them.
