Anyone who has seen the film Hotel Rwanda, will remember how those most shocking and unbelievable atrocities were ignored by the rest of the world, particularly the US, who reckoned it was not their problem.

They cannot blame ignorance any longer, nobody can. We cannot fail to act knowing that genocide continues to be a real threat, while Blair has previcated for more than two years.

Blair’s pledge to start talking now is too late, and naturally he is supporting his brother-in-war over this, rather than standing on his own two feet. Earlier this month, the Shadow International Development Secretary, Andrew Mitchell called on Blair to intervene to avert imminent genocide in the stricken Sudanese region of Darfur. Perhaps he had too many domestic problems on his hands then.

Maybe he has since listened to George Clooney’s urgent warning (the US equivalent to our Bob Geldof), to the UN security council last week: “After September 30, you won’t need the UN. You will simply need men with shovels and bleached white linen.â€?

Desmond Tutu has pleaded for Blair to act in the face of further genocide and questions whether Sudan’s rich oil reserves is influencing how the UN deals with this desperate situation. China, France and Russia, all members of the UN security council, they do business with the government of Sudan and are reluctant to jeopardise their commercial relationships.

Archbishop Tutu says there is something we can all do, we can pray for Darfur today, as well as ask our elected representatives to call for a significant UN force with an effective mandate to protect the civilians in Darfur. I shall be writing off to my MP straight away, that’s something we can all do.

As a former active member of Amnesty International, I know that this organisation believes in the power of the pen, that we can all do something to make a difference for Darfur by bombarding our political leaders with letters of protest against injustice. As today is Global Day for Darfur, we must all do what we can to get the message across, however small it may seem.
