UKIP leader Nigel Farage responded to Adam Afriyie's position on an EU Refurendum in 2014, telling BBC One's Andrew Marr Show that David Cameron's changing stance has left people unsure of what to believe.
"What Adam Afriyie has done is he has put his finger on the real problem and that is, four years ago Mr Cameron gave us a cast-iron guarantee of a referendum.
"This time last year he was saying 'no referendum' and he's now saying there should be a referendum and people aren't quite sure what to believe."
