THE HAT SQUAD: MARGARET THATCHER

Baroness Margaret Thatcher has passed away.  She was the only female prime minister of Great Britain and the only one of the 20th Century to have served three consecutive terms in the post.  She was such a commanding presence on the world stage that she will continue to have her life portrayed in the Toobworld Dynamic across many TV dimensions, in much the same way has Marilyn Monroe, Abraham Lincoln, and JFK will.

These are the TV portrayals I could find in the IMDb:

Being British shows, I'm not familiar with them.  Some of these last batch could be from Skitlandia as well

If I had to choose one for the main TV Dimension of Earth Prime-Time?  I'm not sure.  Perhaps Sylvia Sims or Lindsey Duncan.....
