Best wishes for John Walker-Smith, his family, colleagues and his supporters on the winning of his appeal against the General Medical Council verdict handed down previously involving allegations of professional misconduct.

I personally have believed you to always been a man of the highest integrity and with the best intentions for all the children you have treated over a long and distinguished career.

My thoughts also go out to your colleagues you served with and who were also involved in the gastrointestinal work you undertook. Particularly Professor Simon Murch I would feel it a further injustice if the GMC did not make a further clear statement and rescinded their published findings.

Sometimes justice can be served by a simple apology.
