Chemical weapons

We hear a terrible tale from a modern day Dr Mengele.

A North Korean scientist says he used experimental chemical weapons on prisoners and stood there taking notes while they died in agony.

Dr Kim tells us: "The purpose of this experiment was to determine how long it takes for a human being to die - we wanted to determine how much gas was necessary to annihilate the whole city of Seoul."

I will be putting this new evidence of North Korea's contempt for life and use of chemical weapons to Foreign Office minister Bill Rammell and asking why is it right for us to intervene against Saddam Hussein but not against Kim Jong-Il?

Democrats

And in Boston Kirsty Wark will be live with the Democrats, asking what Kerry needs to do to if he doesn't want to look stupid on the economy.

She'll be joined by corporate guru Jack Welch and the author of "Lies and the Lying Liars Who Tell Them: A Fair and Balanced Look at the Right" - Al Franken.
