It is surprisingly easy to contact your local MP these days, and you may be surprised by how quickly some of them get on the case.
If you are investigating an issue, or want an issue investigated, our little website over at http://ourlocality.org/getwriting/ gives you a head start and a heads up on progress.
The links at the foot of the page allow you to take a look at (selected) recent activity including public FOI requests, though you’ll need to check each Public Authority’s own website to get complete information (sent directly by email or letter).
You can contact politicians, and even get public transport or road problems looked at.
Give it a go, it is pretty easy.
