As a new law allowing the British government to detain suspects without charge for 42 days has been passed by the House of Commons, David Davis, Conservative MP and Shadow Home Secretary, resigned in protest.

As a conservative, he felt he had to stand for government accountability and the defense of civil liberties.
You may think of him as a British Ron Paul, fiercely independent from his own party. He is not. He is the number 2 of the Conservative Party in the UK.

The BBC News report is here, but I found his speech, which he was not allowed to give in the House of Commons, far more important.
