What is being proposed today is not perfect, but the nature of devolution in Wales since 1997 has not been perfect. In 1997, some in the Liberal Democrats, and some in my own party, argued that what was being proposed by Labour wasn't good enough and that we shouldn't support that, while others said, 'Well, we will take hold of this, this imperfect proposal, in order to try and refine it and build on it.'
