Carl Bildt, former Prime Minister and Foreign Minister of Sweden, shares his perspective from Europe:

What's happening in Poland? Should we worry?

Well, legal niceties aside, within the realm of the treaties, the European Union treaties, agreed, it is fundamental that the laws apply and are respected. And if the Polish constitutional court, loaded with political appointees, now decides that they don't apply in Poland, that sort of undermines the very concept of Polish membership of the European Union. So we'll see what happens. We haven't heard the last of this, but it's a fundamental battle. There's no question about that.
