What does a councillor do?

I have been clearing files from an old laptop, and came across the following in a document from 2009

I may have posted it before, but even so, it's worth repeating to remind myself, and others why we do the tasks ...

"Councillors are elected to be an advocate for the interests of the ward, residents and community groups. They represent the interests of those individuals and groups to the Council and deal with enquiries and representations from constituents."

I'm sure that I lifted the quote from another site, so thanks to whoever it was.
