The Guardian notes this morning that:
Britain must be global leader in free trade, says PM, after Brexit vote and Donald Trump’s election as US president
It's a statement that makes no sense for three reasons.
First: there is no such thing as free trade. There are always rules, and the rules are there for good reason. Most protect us from abuse and fraud. Some collect tax.
Second, the claim assumes others want free trade, but that's not the case. They want to work within strong frameworks of rules.
Third if she wants tariff free trade we already have it with our biggest trading partners via the EU and are giving it up. And the US is not going to make it available.
In which case the claim is utter nonsense.
