To add my two pennies worth...
I agree with Debs that it is a decision for the woman on whether she is ready or suitable for carrying, then nuturing a child through to adulthood and beyond, which is a life long committment. It is a woman's body that creates and supports this new life, and as the woman should have soveriegn rights over that body, if a woman believes she cannot realistically provide a satisfactory life for the infant, with all of life's basic needs and the emotional support it requires, then she alone should have the right to terminate.
However, that stated any decision by her should be made before 20 weeks, unless a major medical complication arises, after which time the embryo has the potential to live without the mother's body. Medical staff have often reported that aborted embryos of over 20 weeks have shown signs of life for some time after. This has indeed caused distress to staff who according to medical journals do not want to carryout abortions unless for pressing medical reasons.
Emotions, physical considerations, practical implications, human rights, and, yes, religion, all are involved in this very complex subject which has few, if any, easy answers. We can only trust and hope that a honourable consensus will avail, with the wise and good establishing a decision that will satisfy the majority in this country.
I am pleased that this is all open to an across party free vote for our politicians to vote with their moral conscience, conforming we trust with the wishes of their constituents, rather than a political view.
But, I do feel that it is a great handicap that there is not a majority of female politicians in Westminster to properly represent the views of woman, and we can only put our faith in men to express our concerns and wishes. May God help them in their task.
