Diolch, Llywydd. I deeply regret the new-found politicking and ducking and weaving on the question of the single market that was apparent yesterday in the UK Labour leader's speech on his vision for a future relationship with the European Union. There are real consequences to leaving the single market for real people. One of those will be that we will lose the right to benefit from clinical trials from the European Medicines Agency. Only EEA and EU member states benefit from clinical trials and treatments, so I'd like to have reassurance from the leader of the house—. And this isn't something you can achieve, by the way, through free and unfettered access; you have to be a member of the single market to benefit from EMA membership and for your citizens to benefit from the clinical trials. Can we have a commitment that you will robustly oppose any attempt by a Government of any colour in Westminster to deny Welsh citizens the access to the best cutting-edge treatment that they can be provided with?
