Straw does claim one liberal credential.
The Guardian What is wrong with this government, and with its predecessors, is that it operates on a case by case basis. It has no feeling for the principles of liberty and, clearly, it has no time for them. For example, the Lords won us a temporary remission by defeating the attempt to restrict trial by jury, but no one should suppose this is more than a temporary respite. Jack Straw and his government will be back. The principles which preserve between them the rule of law and the rights of individuals have been systematically subverted by recent governments.
