"The name of my constituency is Haltemprice and Howden - Haltemprice is derived from a medieval proverb meaning noble endeavour.
Up until yesterday I took a view that what we did in the House of Commons representing our constituents was a noble endeavour because for centuries of forebears we defended the freedom of people. Well, we did, up until yesterday.
This Sunday is the anniversary of Magna Carta, a document that guarantees the fundamental element of British freedom, habeas corpus. The right not to be imprisoned by the state without charge or reason.
But yesterday this house allowed the state to lock up potentially innocent citizens for up to six weeks without charge.
The counter-terrorism bill will, in all probability, be rejected by the House of Lords very firmly. After all, what should they be there for, if not to protect Magna Carta?
But because this is defined as political, not security, the government will be tempted to use the Parliament Act to overrule the Lords.
It has no democratic mandate to do this since 42 days was not in its manifesto. Its legal basis is uncertain to say the least but, purely for political reasons, this government is going to do that.
Because the generic security argument relied on will never go away - technology, development complexity, and so on - we'll next see 56 days, 70 days, then 90 days.
But in truth perhaps 42 days is the one most salient example of the insidious, surreptitious and relentless erosion of fundamental British freedom.
And we will have shortly the most intrusive identity card system in the world. A CCTV camera for every 14 citizens, a DNA database bigger than any dictatorship has, with thousands of innocent children and millions of innocent citizens on it.
We have witnessed an assault on jury trials, a bolt against bad law and its arbitrary use by the state.
And shortcuts with our justice system, which will make our system neither firm nor fair and a creation of a database state opening up our private lives to the prying eyes of official snoopers and exposing our personal data to careless civil servants and criminal hackers.
The state has security powers to clamp down on peaceful protest and so-called hate laws to stifle legitimate debate, whilst those who incite violence get off scot-free.
This cannot go on, it must be stopped, and for that reason today I feel it is incumbent on me to take a stand.
I will be resigning my membership of this House and I intend to force a byelection in Haltemprice and Howden.
Now I will not fight it on the government's general record. There's no point repeating Crewe and Nantwich.
I won't fight it on my personal record - I am just a piece in this great chess game.
I will fight it, I will argue this byelection against the slow strangulation of fundamental British freedoms by this government.
Now, that may mean I have made my last speech to the House. It's possible. And of course that would be a cause of deep regret to me. But at least my electorate and the nation, as a whole, would have had the opportunity to debate and consider one of the most fundamental issues of our day.
The ever-intrusive power of the state on our lives, the loss of privacy, the loss of freedom and a steady attrition undermining the rule of law. And if they do send me back here, it will be with a single, simple message - that the monstrosity of a law that we passed yesterday will not stand.
