Mark Thatcher: It is without doubt a very sad moment
Mark Thatcher has paid tribute to his mother and expressed thanks for the messages of support.
My mother was blessed with a long life and a very full one.
However the inevitability or the inevitable conclusion may appear of the recent illness that she suffered, it is no easier for us to bear in what is without doubt a very sad moment.
We have quite simply been overwhelmed by messages of support, condolence of every type from far and wide and I know that my mother would be pleased they have come from people of all walks of life.
Mark Thatcher says his mother would be "humbled" by the presence of The Queen at her funeral.
He added: "I would like to say how enormously proud and equally grateful we are that Her Majesty has agreed to attend the ceremony next week in St Paul’s and I know my mother would be greatly honoured as well as humbled by her presence."
