Bite the Ballot, which launched this year, is a not-for-profit organisation aimed at promoting engagement in the democratic process and voter registration among 16- to-24-year-olds. It is the sister campaign of Rock the Vote, the more established US drive.
Its immediate aim is to register 500,000 of its target demographic to vote before the 2015 General Election.
Edwards, the founder of SB.TV, has thrown his weight behind the initiative by creating video content to drum up interest among young people.
As well as the PM's backing, Labour leader Ed Miliband and deputy prime minister Nick Clegg have also thrown their weight behind the push.
The telecoms partner will be able to use Bite the Ballot’s name and image rights, and have access to events and other prospect data gathering opportunities.
In return, Bite the Ballot seeks funding and the opportunity to address the brand’s database of relevant customers via CSR-based marketing.
The central focus for the group is the establishment of a National Voter Registration Day to be held on 5 February, chosen as this is the anniversary of the 1832 Great Reform Act which introduced fairer voting to the UK.
On the day, the campaign will run events at hundreds of schools and youth groups throughout the UK with the aim of registering more than 250,000 young people to vote in 24 hours.
The Guinness Book of records will monitor activity in order to establish whether it qualifies as a record.
