From a press conference given by British Prime Minister Margaret Thatcher yesterday in England:

Q. Prime Minister, after the Reykjavik summit there was some concern in Western Europe over what had been talked about there and nearly decided. After the Reykjavik summit, there was some concern in Western Europe among the allies. I am wondering after your talk today with Mr. Gorbachev and your communication with President Reagan are you sure that after this summit there will be no surprises for the allies?

A. I do not think there will be any surprises after this summit. I obviously hope and believe that as Mr. Gorbachev and I were talking about the way ahead, I am sure that the president will be talking the whole time about the way ahead -- both on arms control and on the larger human relationship because it is even more important with perestroika and glasnost.

But I have always taken the view that when you go to summits, they need to be very well prepared. And after all, the one on the intermediate nuclear weapons is very well prepared, and they are getting on quite well -- very well with the 50 percent reductions. And then, in the course of the summit, new ideas may come up. After all, that is what often happens when you are talking. You see things either from a different aspect or you see things -- you lay stress on different things, which makes new possibilities, or you have a wholly new idea. That is good if you do get them but then you do not make any commitments. You go away and work them up and work them out.

So I am not expecting any -- when you say "surprise," I am not expecting any shocks. . . . If there are new ideas which are hopeful, then I will be the first to welcome them and be the first to try to help work them out.
