Thatcher returns home from diplomatic tour
Prime Minister Margaret Thatcher flew in to London's Heathrow Airport early Sunday, concluding a six-day round-the-world diplomatic tour. At Camp David last Saturday, she spoke with President Reagan who she said agreed that the US will not deploy its controversial ''star wars'' missile defense system before holding negotiations with the Soviet Union. She endorsed research on the star wars program but stopped short of blessing its eventual deployment.
