Peter Oborne blogs about the above and the background (Foreign Office papers) leading up to that speech. It makes fascinating material and is well worth the time spent reading all 42 documents. What is equally interesting is the views of her Europhile ministers and officials.
Amongst the papers is the transcript of an interview Margaret Thatcher gave Jimmy Young on Radio 2 - her answers and the views contained therein are sorely missed today.
Absolutely a must read! Enjoy!
