Principal Authority Ward Cllrs are often awarded small environmental improvement budgets etc, and they are empowered to decide how to attempt to spend it. A parish council is entiltled to approach the PA Ward Cllr and offer their views about how the budget is spent but ultimately that is all they can do. If they make one recomendation they can offer a different one but the ward cllr might argue they can't make their minds up and won't pay any further attention
