"The photographs published of your clients on holiday (one of Mr and Mrs Bowles and another cropped to show only Sebastian) ..."
I will come back to the cropping in a moment:
"... were taken from Mr Bowles Facebook page on Friday at a time when they were openly accessible. We note that the page's privacy settings have now been increased and as per your request, we have removed these photographs from the website."
Then they say:
"Your clients have our deepest sympathy and we have no wish to add to their distress. We have now circulated an internal warning detailing the issues raised in your letter of 17 March and setting out your clients' concerns."
