Today is about facts. There has been a lot of debate; there have been lots of accusations that we over here don't understand what's going on, but now the time for rhetoric is over. This is about a reasoned argument against a Bill that will weaken this Assembly. Llywydd, tonight, we'll see a Labour Government vote with the Tories and UKIP to support Westminster's EU withdrawal Bill, a Bill that is designed to take powers back under Westminster's control, and it's as simple as that. The body of evidence, public opinion and even their own party leader are against them.

We heard from the Chair of the committee who's just accepted that not a single measure of the tests set by the cross-party external affairs committee was met. Labour's own party leader called it a 'power grab', while the Conservative Prime Minister is praising their actions. Members opposite, I know that many of you believe in devolution and, for this reason, I'm appealing to you to take a stand today. Join us in defending Wales. Join us in standing up for devolution. If you take the party whip, if you follow your front bench, know that this institution will be weaker for it.

Llywydd, I know that through arduous discussions with Westminster, concessions have been achieved. This deal, however, does not deliver on the targets set out by Ministers themselves. In a lecture yesterday, the finance Secretary outlined in detail how the Joint Ministerial Committee is not fit for purpose, yet this deal commits us to using that very committee to protect our powers. The Assembly lawyers have highlighted the risk to devolution posed by this Bill, and the cross-party committees that took a look at these matters agree. Even last week, the environment Cabinet Secretary complained that Westminster had failed to consult her before publishing a new consultation. Westminster are breaking this agreement before it's even in force.

Llywydd, there will be heated contributions to this debate, I've no doubt, but I once again want to appeal to reason. If you believe in Wales, if you believe in devolution, if you believe that it is this Assembly and not Westminster that best serves our people, vote against this motion; vote for devolution; vote for Wales.
