"She was our guardian, friend and protector. She never once allowed her unfaltering love for us to go unspoken or undemonstrated. She will always be remembered for her amazing public work. But behind the media glare, to us, just two loving children, she was quite simply the best mother in the world. We would say that wouldn't we. But we miss her. She kissed us last thing at night. Her beaming smile greeted us from school. She laughed hysterically and uncontrollably when sharing something silly she might have said or done that day. She encouraged us when we were nervous or unsure. She - like our father - was determined to provide us with a stable and secure childhood."
