The list of people putting forward candidate sites for the LDP is not published by the council. The documents submitting each candidate site are available for inspection at the council offices should you wish.
Councillors are required to declare a personal interest where the matter under debate at a council meeting would affect their well being to a greater extent than other taxpayers in their ward. Having done so they can continue to take part and vote on issues. If that interest is so significant that it is likely to prejudice their ability to judge the public interest then they must declare a prejudicial interest and not participate. I would expect that if someone simply attends a pub it would fall into the former rather than the latter category.
Cllr Williams tells me that PEN041 has been withdrawn by the applicant and so the council will likewise withdraw its support - I think it was marked in the wrong place on the map when it was submitted.
I trust this answers your questions
