Outside the conference hall in Birmingham a key group of voters was listening to David Cameron's every word. In November they will go to the polls in Corby in a by-election sparked by the resignation of MP Louise Mensch. Here's what they thought of the speech.
OVERVIEW OF ENTIRE SPEECH
Denis Martin: "I thought it was an attack on working class people, we are going to cut all your benefit.. It's cutting people's livelihoods in a tough economy."
Marcus Learoyd: "I thought that Ed Miliband seemed like a boy in shorts compared to Cameron the man."
CAMERON'S ATTACKS ON LABOUR
Megan Long: "I thought the attacks on Labour were a bit cheap... They should stop using Labour's mistakes to persude us to vote for them."
Marcus Learoyd: "I've said it each week, it just irritates me [the personal attacks], sometimes it's the party, sometimes it's the person."
CAMERON ON THE FAMILY
Dan Kantorowich: "I thought the reference to his family was a bit tacky and a bit American. I think he should have addressed it in a more restrained way."
Marcus Learoyd: "I think he was quite heartfelt and genuine. I think it was a valid point about before people would have seen his son's wheelchair before the child."
CAMERON ON WELFARE
Christopher Hughes: "I have worked continuously for 17 years but was made redundant due to cut backs but I don't want to be tarred with the same brush as those [seeking benefits] sitting at home playing computer games."
