I guess you don’t want her to be with her husband. Is that what you are saying????????
No, not at all! Her wishes are paramount.
But, having been in many of the resting places of the great leaders all over the USA and Europe, I believe she deserves a place where the many who admire her can visit and contemplate her accomplishments / place in history. Westminster Abby has many interned who, IMHO, are not near the leader and significance of Margaret Thatcher.
