First of all, I don't begrudge his party's ability to provide us with entertainment, as he rightly pointed out. But, turning to the points that he makes, first of all, the issue is not devolved, as he knows, but, in terms of the principle of it, I don't agree with him that the point of Brexit is wholesale deregulation. Our financial services sector will still have to operate in the European market. If it doesn't follow the rules of the European market, it won't be able to operate there, and that will have enormous consequences for jobs, not just in Wales, but also in the rest of the UK, particularly the City. The City has been a place where a great deal of European operations have taken place. If the regulations in the UK are substantially different, people won't come to the UK, because they want to operate in a bigger market.

Secondly, we have to remember that the financial crash of 2007 was caused, at least in great part, by deregulation of financial services, and the fact that an opportunity was given to irresponsible financiers to play around with people's money, to lend to people who had no hope of paying them back, and the financial system collapsed as a result of it. So, from my perspective, yes, regulation has to be proportionate, but it has to be there because, bluntly, given what we saw in 2007-08, there are some who work in the large financial centres in this world who cannot be trusted with other people's money.
