[Albion Wilde]

Yes the Queen Mother was the head of the church

Queen Elizabeth II was not the Queen Mother. Elizabeth Bowes-Lyon was the Queen Mother; she died years ago.

[OneVike]

What ever, the moment she died, the new Queen became the only living Queen Mother, and she assumed the position as the head of the Anglican Church of England.

Throughout history, the one who is alive is considered the queen mother, not the dead one any more.
