Speaking at the Leveson Inquiry today (May 10), Coulson confirmed that the then-leader of the Opposition asked him about hacking in 2007 before offering him the job of director of communications of the Conservative Party.
Coulson said that he told Cameron he had no knowledge of phone hacking at the Sunday paper beyond that which had led to the jailing of Clive Goodman and Glenn Mulcaire in January of that year.
"I was able to repeat what I had said publicly... that I knew nothing about the Clive Goodman and Glenn Mulcaire case in terms of what they did," Coulson said.
He added that he could not recall any instances where Cameron had quizzed him further on hacking after a number of reports regarding the practice were published in The Guardian in 2009.
Other matters discussed during Coulson's examination at the inquiry included his exposure to secret material, whether his connections to Rebekah Brooks helped him win the job with Cameron, and his possession of £40,000 shares in News Corp, which he continued to hold during his time as director of communications.
Coulson denied that his connection to Brooks was the "elephant in the room" of his appointment and said of his transition from media to politics: "I had been the editor of a national newspaper for many years that involves politics as we have discussed.
"I was dealing with issues, I ran campaigns. I aimed to be in tune with the readership, which was vast. Those things I'm sure were attractive."
