The fact the US has free speech zones suggests that free speech is in fact not free throughout the country.
However, if we look at the laws laid out in both countries, they are practically the same. The US first amendment allows freedom of expression, caveated with exceptions for inciting hate and defamation, the caveat being that any state can hold such action as unlawful and charge someone in a court of law. Looking at UK law, which incorporates the European law on human rights, we also have the freedom of expression with the exception of threatening and insulting words.
Personally, if you are a public figure and make such statements as this woman did, I think you should at least run the risk of lawful punishment, it's barely going to amount to much if anything but it might make her think twice in future.
