Today I received this reply back from the West Berkshire Council monitoring officer:
My apologies for not getting back to you but there is very little I can add to my previous response.
However in answer to your specific questions regarding 'the procedure (as was)' as to the information requested from each councillor, each member was provided with a pre-printed form from Shaw & Sons (Cat. No. LGA1). The guidance notes to that form provide in respect of question 6: 'If you are employed or have been appointed give in this section the name of the person or body who employs you or appointed you. Please indicate whichever applies deleting the appropriate words in square brackets.'
Cllr Stansfeld followed the guidance in his response as far as I can see from his response. There was no request for details of the address of the body referred to under this section and as I mentioned previously there is no requirement to provide an address.
In regard to your second question you ask if councillors were expected to list all bodies who employ/appointed them. I would expect that any member who disclosed this information would disclose all such bodies. The completion of the form was a matter for each member, as I'm sure you are aware, and if they had any concerns they could have consulted myself as Monitoring Officer.
As far the other company you mention is concerned I have checked with Councillor Stanford and he is no longer involved with it. I am not responsible for the currency of his Linked in account so I am unable to comment as to whether it is out of date.
Once again apologies for not responding sooner
