Yes 1ofmany, I get e.mails from the "whatdotheyknow.com site of any new questions or updates posted to the site concerning Wirral Borough Clouncil so I did notice that you had asked the question.
Just be aware that Wirral are particularly good at fobbing people off using a number of tactics if they do not want to answer the question but I will keep in touch with your question.
Glad to be of help and just to re-itterate for any other members of the public who want to ask FOI questions,
www.whatdotheyknow.com is a web site where you can post your question (to any organisation falling under the FOI legislation)and receive updates as to answers or even reminders that the authority being asked the question have gone over their 20 day allowed limit. Far easier to do than write via snail mail.
