She's an interesting character. She represents the British standard of Libertarianism in a lot of ways; it's basically that whole "stand on your own two feet" approach to Welfare Libertarians often have in the USA, but with far less of the civil liberties people often talk of. The British, Thatcherite brand of "Libertarianism" is much more authoritarian. Though I disagree with his political views
Alex Massie is one British Libertarian academic who had some interesting things to say about Mrs. Thatcher's legacy and how she would have viewed the Britain she created.
I understand Nigel Farage has been doing some things to change the stuffier, more recognisably right-wing attitudes of Libertarianism here, such as in his more open minded approach to drug legalisation (he ascribes to the "drugs are bad" camp but he believes the current approach doesn't work) but he's still infected with the old virus. He still talks about how Britain is a Christian country and so on, let's not even go there about the imbeciles and eccentrics that make up the party membership. But still, it's interesting to compare the Libertarian schools of thought in the UK with those in the USA.
I often wonder if certain camps of American Libertarians are closer to Thatcher's ideology than I think. They'd probably take truck with her anti gun stance and preference for surveillance, though. When British Conservatives talk about the "nanny state" it usually has less to do with lack of privacy/liberty and more to do with us supporting benefits "scroungers".
