[19] In April 2011, cabinet minister Chris Huhne threatened legal action over alleged untruths disseminated by Conservatives opposed to the alternative vote system.

[20] At a Cabinet meeting on 2 May, Huhne was strongly critical of Conservative colleagues about the No2AV campaign material, in particular targeting a key 'No' leaflet showing a newborn baby with the slogan "She needs a maternity unit, not an alternative voting system".

[21] On the day of the referendum, it was reported in the New Statesman that David Blunkett had admitted that the claim that introducing the AV system would be more expensive had been exaggerated.

[22] In May 2011, three days before the referendum vote, The Guardian newspaper released an analysis of the accounts of donations to the campaign, showing that it been funded almost exclusively by Conservative Party donors.

[23] The figures obtained by the Guardian do not include donations received by the NoToAV campaign prior to the passing of the Parliamentary Voting System and Constituencies Act 2011 by Parliament in February 2011.
