In the light of the Government’s apparent enthusiasm for greater democracy, allow me to recommend a couple of websites that will enable you to keep close tabs on what your MP is up to on your behalf. Checking MP’s voting records can be interesting, and could perhaps provide you with some questions to fire at him/her during the next election campaign.

Bookmark them for 2011, and keep tabs on your ‘representatives’.

Thank you, Tom.
When I remember the name of my quite remarkably boring MP, I’ll check out exactly what he has been up to.
Thank you for the reminder, I have to write to him!
Araminta, you can feed in the name of any MP to get information, not just your own constituency
