David Blunkett's letter of resignation and Tony Blair's response:
This letter is to tender my resignation as Secretary of State for Work and Pensions.
I want to thank you for your sustained and unwavering support through these difficult days and weeks.
I have chosen to stand down to protect you and the Government from the continuing speculations made against me.
Let me be clear, what has happened is my mistake. As you know, I acknowledged this last weekend. I believe that to allow this matter to obscure the agenda of Government and to undermine our message would be to let you down. I have not intention of doing so.
I will continue to contribute in any way I can to the reform and delivery of public services and to the strength and clarity which your leadership brings to our government.
I am deeply grateful for all you have done and will do as prime minister and for your support to me over the years.
With best wishes
I accept your resignation with regret.
I want to pay tribute to the extraordinary contribution you have made to the Government and to public life. You have overcome great challenges to achieve great things. There are few who can make such a claim.
As I said today in the House, whatever mistakes you have made, you are a decent and honourable man.
I am certain that you will continue to make a great contribution to public life.
