news – and won't be looked upon kindly by Downing Street." This ledDaniel Hannan to say: "A referendum on EU membership is starting to feel unavoidable. Boris Johnson's support for the People's Pledge is just the latest token of a changed atmosphere." The campaign also has the support of the Green London Mayoral candidate Jenny Jones.

Specifically, it asked voters to sign up to a pledge via the campaign's website to only support such candidates. In addition to showing the total number of signatories, the campaign would also present those figures broken down by constituency.
