Today comes a further innovation for Conservative Central Office, allowing the public, for the first time, to "co-sponsor" a Bill online. The innovation of co-sponsoring bills on social media was launched in the United States earlier this year. It allows people to show their support for issues and ideas they care about and track the progress of bills in the House of Representatives. Users can become virtual co-sponsors of bills by logging on via Facebook and can then choose to share that status with friends. Citizen co-sponsors are updated on the status of their bills through the Facebook app as they move through the legislative process. It's not, of course, a formal part of the Parliamentary process. But it will increase the pressure on Labour and Liberal Democrat MPs who think they can ignore the public's desire for a say on Europe.
