I’ve just been asked to do Newsnight tonight to take part in a discussion about great speeches. The peg is Martin Luther King Day. The great human rights leader has been trending on twitter all day as people recall his achievements and some of his great lines and speeches.

At one point it seemed they were going to have Luther King’s speechwriter, Clarence Jones, who alas is now unable to do it, so it will be with another as yet unidentified speechwriter and Tom Hooper, the director of the runaway hit and near certain Oscar winner The King’s Speech.

I have my own views about the question, which I will air tonight, but meanwhile please feel free to make suggestions on what you consider to be the great speeches of this century and last.
