The Prime Minister said voters were not ‘ fully sure ’ about the Tories at the last election , but would back them this time . Mr Cameron made the remarks in an interview with the BBC ’ s Evan Davis in the second of a series of special election interviews . The PM also revealed that nothing made him ‘ more angry ’ than the Tories being called the party of the rich and admitted there were people who did not pay tax in Britain who ‘ damn well should ’ . Mr Cameron ’ s remarks came after the Deputy Prime Minister Nick Clegg insisted the Tories were getting rattled because they knew they could not win an outright majority next month . Polls have consistently put the Tories and Labour Party neck and neck with just three weeks to go before polling day . But Mr Cameron insisted voters would come round to the Tories in the final days of the campaign . He said : ‘ At the last election when we came close I think frankly people were very worried about the state of the economy , we were teetering on the brink and they weren ’ t fully sure we had all the ideas and plans . ‘ What I would say is this time people can see a track record . An economy turned round , more people in work , the deficit paid down , Britain on the brink of something special . ‘ This time I believe they can put their trust in me and in the Conservative Party to deliver that better future for the country. ’ The PM also revealed that nothing made him ‘ more angry ’ than the Tories being called the party of the rich and admitted there were people who did not pay tax in Britain who ‘ damn well should ' Mr Cameron made the remarks in an interview with the BBC ’ s Evan Davis in the second of a series of special election interviews .

The Tories have said details of this will be set out after the election , and Mr Cameron said : `` What we 're proposing is totally affordable and doable . '' Despite his planned welfare cuts , Mr Cameron said the Tories were not the party of the rich . He said : 'Look there will be people watching this programme who go out , who work damn hard every day , they pay their taxes . 'They don ’ t pay their taxes so that people who can work choose not to . You know , the reward sometimes for irresponsible behaviour can drive people mad – can drive me mad and that ’ s one of the reasons to reform welfare . ' He said that accusations that the Conservatives are `` the party of the rich '' make him `` more angry than almost anything else '' . He said : 'What infuriates me so much about this is I think of what we ’ ve done . We ’ ve taken three million of the lowest paid people out of tax . 'It ’ s the people at the bottom end that I care about . That ’ s what this government has been about – more good schools for children from low income backgrounds getting people into work who ’ ve been unemployed . ’
