Hey, I just wrote to my local MP using text that I blatantly plagiarised from Podnosh. (I did modify his text a bit) Here's what I sent:

I am writing to ask you to sign EDM 2141, tabled in July by Lib Dem MP Jo Swinson, in support of the Free Our Bills campaign by charity MySociety.

MySociety’s pioneering work is recognised worldwide. They are seeking Parliament’s assistance to enable the public to see the laws being drafted and published on their behalf more easily.

Although the motion has been tabled by a LibDem member, I would note that senior figures in your own party have spoken in favour of freeing public data. Not least Tom Watson, who’s work as Cabinet Office Minister is encouraging collaboration on new ways to get public value from public data. This is precisely what MySociety is proposing for Westminster.

MySociety’s track record shows that they can and will deliver. They are proposing changes which will take little time, cost little money, and have no material impact on current working practices. I believe that this MySociety proposal will further promote greater public engagement and understand with the UK political process.

I urge you to show your support for this important principle; and to take a few moments to sign the EDM in question.

If you don't know who you're local MP is Mysociety have got that covered too. See TheyWorkForYou.com
